7008 - Block Diagram


64K x 8 Dual-Port RAM

The 7008 is a high-speed 64K x 8 Dual-Port Static RAM designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.


  • True Dual-Ported memory cells which allow simultaneous reads of the same memory location
  • 7008 easily expands data bus width to 16 bits or more
  • Interrupt Flag
  • On-chip port arbitration logic
  • Full on-chip hardware support of semaphore signaling between ports
  • Fully asynchronous operation from either port
  • TTL-compatible, single 5V (±10%) power supply
  • Available in 84-pin PGA, PLCC, and 100-pin TQFP packages
  • Industrial temperature range (-40C to +85C) is available
