SYNCHRONOUS PIPELINED
DUAL-PORT STATIC RAM
IDT709379/69L
Features
◆ _{True Dual-Ported memory cells which allow simultaneous}
access of the same memory location
◆ _{High-speed clock to data access}
– Commercial: 6.5/7.5/9/12ns (max.)
– Insustrial: 9ns (max.)
◆ _{Low-power operation}
– IDT709379/69L
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 6.5ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 10ns cycle time, 100MHz operation in Pipelined output mode
◆ _{Separate upper-byte and lower-byte controls for}
multiplexed bus and bus matching compatibility
