The IDT7M1002 is a 16K x 32 high-speed CMOS Dual-Port Static RAM Module constructed on a co-fired ceramic substrate using four 16K x 8 (IDT7006) Dual-Port Static RAMs in surface-mounted LCC packages. The IDT7M1002 module is designed to be used as stand-alone 512K Dual-Port RAM or as a combination Master/Slave Dual-Port RAM for 64-bit or more word width systems. Using the IDT Master/Slave approach in such system applications results in full-speed, errorfree operation without the need for additional discrete logic. The 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 additional control signals SEM and INT.
