... P ower Supply Pin ss 6 Function (In Detail) Address Inputs: A0-A12 are sampled during the ACTIVE command (row-address A0-A12) and READ/WRITE command (column address A0-A9 (x16); A0-A9, A11 (x8); with A10 defining auto precharge) to select one location out of the memory array in the respective bank. A10 is sampled during a PRECHARGE command to determine if all banks are to be precharged (A10 HIGH) or bank selected by BA0, BA1 (LOW). The address inputs also provide the op-code during a LOAD MODE REGISTER command. Bank Select Address: BA0 and BA1 defines which bank the ACTIVE, READ, WRITE or PRECHARGE command is being applied. CAS, in conjunction with the RAS and WE, forms the device command. See the " ...

... The row being accessed will be precharged at the end of the WRITE burst, if AUTO PRECHARGE is selected. If AUTO PRECHARGE is not selected, the row will remain open for subsequent accesses. A memory array is written with corresponding input data on DQ’s and DQM input logic level appearing at the same time. Data will be written to memory when DQM signal is LOW. When DQM is HIGH, the corresponding data inputs will be ignored, and a WRITE will not be executed to that byte/column location. PRECHARGE The PRECHARGE command is used to deactivate the open row in a particular bank or the open row in all banks. ...

IS42S86400B, IS42/45S16320B FUNCTIONAL DESCRIPTION The 512Mb SDRAMs are quad-bank DRAMs which operate at 3.3V and include a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the 134,217,728-bit banks is organized as 8,192 rows by 1024 columns by 16 bits or 8192 rows by 2048 columns by 8bits. Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin ...

IS42S86400B, IS42/45S16320B REGISTER DEFINITION Mode Register The mode register is used to define the specific mode of operation of the SDRAM. This definition includes the selection of a burst length, a burst type, a CAS latency, an operating mode and a write burst mode, as shown in MODE REGISTER DEFINITION. The mode register is programmed via the LOAD MODE REGISTER command and will retain the stored information until it is programmed again or the device loses power.

Page 25
IS42S86400B, IS42/45S16320B BURST LENGTH Read and write accesses to the SDRAM are burst oriented, with the burst length being programmable, as shown in MODE REGISTER DEFINITION. The burst length deter- mines the maximum number of column locations that can be accessed for a given READ or WRITE command. Burst lengths locations are available for both the sequential and the interleaved burst types, and a full-page burst is available for the sequential type. The full-page burst is used in conjunction with the BURST TERMINATE command to generate arbitrary burst lengths. Reserved states should not be used, as unknown operation or incompatibility with future versions may result. When a READ or WRITE command is issued, a block of columns equal to the burst length is effectively selected. All accesses for that burst take place within this block, mean- ing that the burst will wrap within the block if a boundary BURST DEFINITION Burst Starting Column Length Address ...
Page 26
IS42S86400B, IS42/45S16320B CAS Latency The CAS latency is the delay, in clock cycles, between the registration of a READ command and the availability of the first piece of output data. The latency can be set to two or three clocks READ command is registered at clock edge n, and the latency is m clocks, the data will be available by clock edge The DQs will start driving as a result of the clock edge one cycle earlier ( 1), and provided that the relevant access times are met, the data will be valid by clock edge For example, assuming that the clock cycle time is such that all relevant access times are met READ command is registered at T0 and the latency is programmed to two clocks, the DQs will start driving ...
Page 27
IS42S86400B, IS42/45S16320B CHIP OPERATION BANK/ROW ACTIVATION Before any READ or WRITE commands can be issued to a bank within the SDRAM, a row in that bank must be “opened.” This is accomplished via the ACTIVE command, which selects both the bank and the row to be activated (see Activating Specific Row Within Specific Bank). After opening a row (issuing an ACTIVE command), a READ or WRITE command may be issued to that row, subject to the t specification. Minimum t rcd rcd the clock period and rounded up to the next whole number to determine the earliest clock edge after the ACTIVE command on which a READ or WRITE command can be entered. For example specification of 15ns with a rcd 143 MHz clock (7ns period) results in 2.14 clocks, rounded to 3. This is reflected in the following example, which cov- ...
Page 28
IS42S86400B, IS42/45S16320B READS READ bursts are initiated with a READ command, as shown in the READ COMMAND diagram. The starting column and bank addresses are provided with the READ command, and auto precharge is either enabled or disabled for that burst access. If auto precharge is enabled, the row being accessed is precharged at the completion of the burst. For the generic READ commands used in the fol- lowing illustrations, auto precharge is disabled. During READ bursts, the valid data-out element from the starting column address will be available following the CAS latency after the READ command. Each subsequent data-out element will be valid by the next positive clock edge. The CAS Latency diagram shows general timing for each possible CAS latency setting. Upon completion of a burst, assuming no other commands have been initiated, the DQs will go High-Z. A full-page burst ...

Following the PRECHARGE command, a subsequent command to the same bank cannot be issued until t is met. Note that part of the row precharge time is rp hidden during the access of the last data element(s). In the case of a fixed-length burst being executed to completion, a PRECHARGE command issued at the optimum time (as described above) provides the same operation that would result ...

IS42S86400B, IS42/45S16320B PRECHARGE The PRECHARGE command (see figure) is used to deac- tivate the open row in a particular bank or the open row in all banks bank(s) will be available for a subsequent row access some specified time (t ) after the PRECHARGE rp command is issued. Input A10 determines whether one or all banks are to be precharged, and in the case where only one bank precharged, inputs BA0, BA1 select the bank. When all banks are to be precharged, inputs BA0, BA1 are treated as “Don’t Care.” Once a bank has been precharged the idle state and must be activated prior to any READ or WRITE commands being issued to that bank. POWER-DOWN Power-down occurs if CKE is registered LOW coincident with a NOP or COMMAND INHIBIT when no accesses are in progress. If power-down occurs when all banks are idle, this mode is referred to as precharge power-down; if power-down occurs when there is a row active in either bank, this mode is referred to as active power-down.

IS42S86400B, IS42/45S16320B BURST READ/SINGLE WRITE The burst read/single write mode is entered by programming the write burst mode bit (M9) in the mode register to a logic 1. In this mode, all WRITE commands result in the access of a single column location (burst of one), regardless of the programmed burst length. READ commands access columns according to the programmed burst length and sequence, just as in the normal mode of operation (M9 = 0). CONCURRENT AUTO PRECHARGE An access command (READ or WRITE) to another bank while an access command with auto precharge enabled is executing is not allowed by SDRAMs, unless the SDRAM supports CONCURRENT AUTO PRECHARGE.
