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.
