Description
The IDT70T633/1 is a high-speed 512/256K x 18 Asynchronous
Dual-Port Static RAM. The IDT70T633/1 is designed to be used as a
stand-alone 9216/4608K-bit Dual-Port RAM or as a combination MAS-
TER/SLAVE Dual-Port RAM for 36-bit-or-more word system. Using the
IDT MASTER/SLAVE Dual-Port RAM approach in 36-bit or wider
memory system applications results in full-speed, error-free operation
without the need for additional discrete logic.
This device provides two independent ports with separate control,
address, and I/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. An automatic power down
feature controlled by the chip enables (either
CE0 or CE1) permit the
on-chip circuitry of each port to enter a very low standby power mode.
The IDT70T651/9 has a RapidWrite Mode which allows the designer
to perform back-to-back write operations without pulsing the R/
W input
each cycle. This is especially significant at the 8 and 10ns cycle times of
the IDT70T651/9, easing design considerations at these high perfor-
mance levels.

on one or both ports, controlled by the OPT pins. The power supply for
the core of the device (VDD) remains at 2.5V.
