BiCMOS SYNCHRONOUS DUAL-PORT STATIC MODULE
IDT7M1024
High-density Synchronous Dual-Port SRAM module Architecture based Dual-Port cells Allows full simultaneous access from both ports Synchronous operation set-up clock, hold control, data, address inputs Data input, address, control registers Fast 20ns clock data Self-timed write allows fast write cycle Clock enable feature Single (±10%) power supply Multiple pins decoupling capacitors maximum noise immunity Inputs/outputs directly TTL-compatible
DESCRIPTION:
IDT7M1024 high-speed synchronous Dual-Port Static module constructed co-fired
ramic substrate using four IDT7099 Dual-Port RAMs. IDT7M1024 module designed used standalone 36-bit Dual-Port Static RAM. IDT7M1024 provides true synchronous Dual-Port Static interface. Registered inputs provide very short set-up hold times address, data, critical control inputs. internal registers clocked rising edge clock signal. asynchronous output enable provided ease asynchronous interfacing. internal write pulse width independent HIGH periods clock. This allows shortest possible realized cycle times. Clock enable inputs provided stall operation address data input registers without introducing clock skew very fast interleaved memory applications. data inputs gated control on-chip noise bussed applications. user must guarantee that pins least clock cycle before write attempted. HIGH input clock cycle will power down internal circuitry reduce static power consumption. IDT7M1024 module packaged 142-lead ceramic
