Description The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port Static RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with the IDT70125 “SLAVE” Dual-Port in 18bit-or-more word width systems. Using the IDT MASTER/ SLAVE Dual-Port RAM appr...

  – IDT70121/70125L Active: 500mW (typ.) Standby: 1mW (typ.)
• Fully asychronous operation from either port
• MASTER IDT70121 easily expands data bus width to 18 bits or more using SLAVE IDT70125 chip
• On-chip port arbitration logic (IDT70121 only)
• BUSY output flag on Master; BUSY input on Slave
• INT flag for port-to-port communication
• Battery backup operation—2V data retention
• TTL-compatible, signal 5V (± 10%) power supply
• Available in 52-pin PLCC
• ...

HIGH-SPEED 2K x 9 DUAL-PORT STATIC RAM
The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port Static RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with the IDT70125 “SLAVE” Dual-Port in 18bit-or-more word width systems. Using the IDT MASTER/ SLAVE Dual-Port RAM approach in 18-bit-or-wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. Both devices provide two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power-down feature, controlled by CE, permits the on-chip circui...
