Bus operations
There are five standard bus operations that control the device. These are bus read (random
and page modes), bus write, output disable, standby and automatic standby.
See
summary. Typical glitches of less than 5 ns on chip enable, write enable, and reset pins are
ignored by the memory and do not affect bus operations.
Bus read
Bus read operations read from the memory cells, or specific registers in the command
interface. To speed up the read operation the memory array can be read in page mode
where data is internally read and stored in a page buffer. The page has a size of 8 words (or
16 bytes) and each word in the page is addressed by the address inputs A2-A0 in x 16
mode and A2-A0 plus DQ15A 1 in byte mode.
A valid bus read operation involves setting the desired address on the address inputs,

Bus write
Bus write operations write to the command interface. A valid bus write operation begins by
setting the desired address on the address inputs. The address inputs are latched by the
command interface on the falling edge of chip enable or write enable, whichever occurs last.
The Data inputs/outputs are latched by the command interface on the rising edge of chip
enable or write enable, whichever occurs first. Output enable must remain High, V

Standby
Driving chip enable High in read mode, causes the memory to enter standby mode and the
data inputs/outputs pins are placed in the high-impedance state. To reduce the supply
current to the standby supply current, I
