Functional Description
static RAM (PSRAM) organized as 256K words by 16 bits that
supports an asynchronous memory interface. This device
features advanced circuit design to provide ultra-low active
current. This is ideal for portable applications such as cellular
telephones. The device can be put into standby mode

high-impedance state when: deselected (
LOW, OE is HIGH), or during a write operation (Chip
Enabled and Write Enable WE LOW).
Reading from the device is accomplished by asserting the
Chip Enables (
Enable( OE ) LOW while forcing the Write Enable ( WE ) HIGH.
If Byte Low Enable ( BLE ) is LOW, then data from the memory
location specified by the address pins A0 through A17 will
appear on I/O
then data from memory will appear on I/O
