Due to space limitations, FBGA-packaged components have an abbreviated part mark-
ing that is different from the part number. For a quick conversion of an FBGA code, see
the FBGA part marking decoder on Micron’s Web site, www.micron.com/decoder.
The Micron
containing 268,435,456 bits. It is internally configured as a quad-bank DRAM with a syn-
chronous interface (all signals are registered on the positive edge of the clock signal,
CLK). Each of the 67,108,864-bit banks is organized as 4,096 rows by 512 columns by 32
bits.
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 with the registration of an ACTIVE command, which is then
followed by a READ or WRITE command. The address bits registered coincident with the
ACTIVE command are used to select the bank and row to be accessed (BA0, BA1 select
the bank; A0–A11 select the row). The address bits registered coincident with the READ
or WRITE command are used to select the starting column location for the burst access.
The SDRAM provides for programmable read or write burst lengths of 1, 2, 4, or 8 loca-
tions, or the full page, with a burst terminate option. An auto precharge function may be
enabled to provide a self-timed row precharge that is initiated at the end of the burst
sequence.
The 256Mb SDRAM uses an internal pipelined architecture to achieve high-speed oper-
ation. This architecture is compatible with the 2n rule of prefetch architectures, but it
also allows the column address to be changed on every clock cycle to achieve a high-
