Description
The IDT7037 is a high-speed 32K x 18 Dual-Port Static RAM. The IDT7037 is designed to be used as a stand-alone 576K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

Features
◆ True Dual-Ported memory cells which allow simultaneous reads of the same memory location
◆ High-speed access
   – Commercial: 15/20ns (max.)
◆ Low-power operation
   – IDT7037L
      Active: 1W (typ.)
      Standby: 1mW (typ.)
◆ Dual chip enables allow for depth expansion without external logic
◆ IDT7037 easily expands data bus width to 36 bits or more using the Master/Slave select when cascading more than one device
◆ M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave
◆ Interrupt Flag
◆ On-chip port arbitration logic
◆ Full on-chip hardware support of semaphore signaling between ports
◆ Fully asynchronous operation from either port
◆ Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility
◆ TTL-compatible, single 5V (±10%) power supply
◆ Available in a 100-pin TQFP
◆ Industrial temperature range (–40°C to +85°C) is available for selected speeds
