DESCRIPTION:
The lDT61298SA is a 262,144-bit high-speed static RAM
organized as 64K x 4. It is fabricated using IDT鈥檚 high-
performance, high-reliability CMOS technology. This state-of-
the-art technology, combined with innovative circuit design
techniques, provides a cost-effective approach for memory
intensive applications.
The IDT61298SA features two memory control functions:
Chip Select (
CS
) and Output Enable (
OE
). These two func-
tions greatly enhance the IDT61298SA's overall flexibility in
high-speed memory applications.
Access times as fast as 12ns are available. The IDT61298SA
offers a reduced power standby mode, I
SB1
, which enables
the designer to considerably reduce device power require-
ments. This capability significantly decreases system power
and cooling levels, while greatly enhancing system reliability.
All inputs and outputs are TTL-compatible and the device
operates from a single 5 volt supply. Fully static asynchronous
