HIGH-SPEED 128K x 8
SYNCHRONOUS PIPELINED
DUAL-PORT STATIC RAM
IDT709099L
Features
◆ True Dual-Ported memory cells which allow simultaneous
access of the same memory location
◆ High-speed clock to data access
– Commercial: 9/12ns (max.)
– Industrial: 9ns (max.)
◆ Low-power operation
– IDT709099L
Active: 1.2W (typ.)
Standby: 2.5mW (typ.)
◆ Flow-Through or Pipelined output mode on either Port via
the FT/PIPE pins
◆ Counter enable and reset features
◆ Dual chip enables allow for depth expansion without
additional logic
◆ Full synchronous operation on both ports
– 4ns setup to clock and 0ns hold on all control, data, and
address inputs
– Data input, address, and control registers
– Fast 9ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 15ns cycle time, 66.7MHz operation in Pipelined output mode
◆ TTL- compatible, single 5V (±10%) power supply
