SYNCHRONOUS DUAL-PORT
STATIC RAM MODULE
Integrated Device Technology, Inc.
ramic substrate using four IDT7099 (4K x 9) Dual-Port RAMs.
The IDT7M1024 module is designed to be used as a stand-
alone 36-bit Dual-Port Static RAM.
FEATURES:
• High-density 4K x 36 Synchronous Dual-Port SRAM
module
The IDT7M1024 provides a true synchronous Dual-Port
Static RAM interface. Registered inputs provide very short
set-up and hold times on address, data, and all critical control
inputs. All internal registers are clocked on the rising edge of
the clock signal. An asynchronous output enable is provided
to ease asynchronous bus interfacing.
The internal write pulse width is independent of the HIGH
and LOW periods of the clock. This allows the shortest
possible realized cycle times. Clock enable inputs are pro-
vided to stall the operation of the address and data input
registers without introducing clock skew for very fast inter-
leaved memory applications.

• Architecture based on Dual-Port RAM cells
— Allows full simultaneous access from both ports
• Synchronous operation
— 4ns set-up to clock, 1ns hold on all control, data, and
address inputs
— Data input, address, and control registers
— Fast 20ns clock to data out
— Self-timed write allows fast write cycle
• Clock enable feature
• Single 5V (±10%) power supply
• Multiple GND pins and decoupling capacitors for maxi-
mum noise immunity
• Inputs/outputs directly TTL-compatible
