DUAL-PORT STATIC RAM

Features

◆

True Dual-Ported memory cells which allow simultaneous

Dual chip enables allow for depth expansion without

additional logic

Full synchronous operation on both ports

– 4ns setup to clock and 1ns hold on all control, data, and

addressinputs

access of the same memory location

High-speed clock to data access

◆

– Commercial:6.5/7.5/9/12/15ns(max.)

– Industrial:12ns (max.)

Low-power operation

◆

– Data input, address, and control registers

– IDT709279/69S

Active:950mW(typ.)

Standby: 5mW (typ.)

– IDT709279/69L

Active:950mW(typ.)

Standby: 1mW (typ.)

Flow-Through or Pipelined output mode on either port via

the FT/PIPE pin

Counter enable and reset features

– Fast 6.5ns clock to data out in the Pipelined output mode

– Self-timedwriteallowsfastcycletime

– 10ns cycle time, 100MHz operation in Pipelined output mode

Separate upper-byte and lower-byte controls for

multiplexed bus and bus matching compatibility

TTL- compatible, single 5V (±10%) power supply

Industrial temperature range (–40°C to +85°C) is

available for selected speeds
