8-Bit High-Speed PSRAM
DESCRIPTION
The MSM548128BL is a 1-Mbit, high-speed and low power CMOS Pseudo Static RAM organized
as 131,072-word
￥
8-bit.
The MSM548128BL is fabricated using silicon gate N well CMOS process. This process, coupled
with single-transistor memory storage cells, permits maximum circuit density, minimum chip
size, and high speed.
MSM548128BL has Self-refresh mode in addition to Address-refresh mode and Auto-refresh
mode. In Self-refresh mode the internal refresh timer and address counter refresh the dynamic
memory cells automatically. This series allows low power consumption when using standby
mode with Self-refresh.
The MSM548128BL also features a static RAM-like write function that writes the data into the
memory cell at the rising edge of
WE
.
The MSM548128BL is pin compatible with CMOS static RAM and 256K pseudo static RAM.
