AMES
The EDI9F416512C is a 32Mb CMOS Static RAM based
on eight 512Kx8 Static RAMs mounted on a multi-lay-
ered epoxy laminate (FR-4) substrate.
A low power version with data retention
(EDI9F416512LP) is also available.
All inputs and outputs are TTL compatible and operate
from a single +5V supply. Fully asynchronous, the
EDI9F416512C requires no clocks or refreshing for
operation.
