1 / 11 page Integrated Device Technology, Inc. FEATURES • High-density 1M/512K CMOS Dual-Port Static RAM module • Fast access times: —Commercial 35, 40ns —Military 40, 50ns • Fully asynchronous read/write operation from either port • Full on-chip hardware support of semaphore signaling between ports • Surface mounted LCC (leadless chip carriers) compo- nents on a 64-pin sidebraze DIP (Dual In-line Package) • Multiple Vcc and GND pins for maximum noise immunity • Single 5V ( ±10%) power supply • Input/outputs directly TTL-compatible DESCRIPTION: The IDT7M1001/IDT7M1003 is a 128K x 8/64K x 8 high- speed CMOS Dual-Port Static RAM module constructed on a multilayer ceramic substrate using eight IDT7006 (16K x 8) Dual-Port RAMs and two IDT FCT138 decoders or depopu- lated using only four IDT7006s and two decoders. This module provides two independent ports with separate control, address, and I/O pins that permit independent and asynchronous access for reads or writes to any location in memory. System performance is enhanced by facilitating port-to-port communication via semaphore ( SEM) “hand- shake” signaling. The IDT7M1001/1003 module is designed to be used as stand-alone Dual-Port RAM where on-chip hardware port arbitration is not needed. It is the users re- sponsibility to ensure data integrity when simultaneously accessing the same memory location from both ports. The IDT7M1001/1003 module is packaged on a multilayer co-fired ceramic 64-pin DIP (Dual In-line Package) with di- mensions of only 3.2" x 0.62" x 0.38". Maximum access times as fast as 35ns over the commercial temperature range are available. All inputs and outputs of the IDT7M1001/1003 are TTL- compatible and operate from a single 5V supply. Fully asyn- chronous circuitry is used, requiring no clocks or refreshing for operation of the module. All IDT military module semiconductor components are manufacured in compliance with the latest revision of MIL- STD-883, Class B, making them ideally suited to applications demanding the highest level of performance and reliability. 128K x 8 64K x 8 CMOS DUAL-PORT STATIC RAM MODULE IDT7M1001 IDT7M1003 Left Port Right Port Description A (0–16)L A (0–16)R Address Inputs I/O (0–7)L I/O (0–7)R Data Inputs/Outputs R/ WL R/ WR Read/Write Enables CSL CSR Chip Select OEL OER Output Enable SEML SEMR Semaphore Control VCC Power GND Ground 2804 tbl 01 PIN CONFIGURATION(1) MILITARY AND COMMERCIAL TEMPERATURE RANGES MARCH 1995 ©1995 Integrated Device Technology, Inc.
