Notes:
1. For a detailed definition of read/write, see the Write Table below.
2. An "X" means don't care, "1" means logic high, and "0" means logic low.
3. The
OE
pin enables the data output and is not sampled with the clock. All signals of the SRAM are sampled synchronously
with the bus clock except for the OE pin.
4. On a write cycle that follows a read cycle,
OE
must be inactive prior to the start of write cycle to allow write data to setup to
the SRAM. OE must also disable the output buffer prior to the finish of a write cycle to ensure the SRAM data hold timings
are met.
