UPD42S17405 - 16M-BIT DYNAMIC RAM

Datasheet Summary

Description

The µPD42S17405, 4217405 are 4,194,304 words by 4 bits CMOS dynamic RAMs with optional EDO.

EDO is a kind of the page mode and is useful for the read operation.

Besides, the µPD42S17405 can execute CAS before RAS self refresh.

Features
