MSM548128BL

131,072-Word ¥ 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.
