General Description
MSM548512L General Description
The MSM548512L is fabricated using OKI's CMOS silicon gate process technology. This process,coupled with single-transister memory storage cells, permits maximum circuit density, minimum chip size and high speed.
MSM548512L has Self-refresh mode in addition to Address-refresh mode and Auto-refresh mode. In the 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 MSM548512L also features a static RAM-like write function that writes the data into the memory cell at the rising edge of WE.
