PRELIMINARY
16Mbit CMOS SRAM
3DS16-325
512K x 32 Bit High-Speed CMOS Static RAM-5.0V Operating
Fast Access Time : 15 or 20ns
Single 5.0 ± 0.5V Power Supply
Power Dissipation
- Standby 80mA
- Operating 540mA (Max.)
TTL Compatible Inputs and Outputs
Fully Static Operation
- No clock or Refresh required
Three State Outputs
Center Power/Ground Pin Configuration
Die Control : CS0#, CS1#, CS2# and
CS3# chip select
The 3DS16-325 is a 16,777,216 - bit high-speed Static Random Access
Memory organized as 4 banks of 262,144 words of 16 bits. Two
banks can operate silmultaneously, giving 32 bit processing.
The 3DS16-325 uses 32 common input and output lines and has
an output enable pin which operates faster than address access
time at read cycle.
Also it allows lower and upper byte access by data control
(UB#, LB#). The device is manufactured using 3D PLUS well
known MCM-V patended technology designed for high-speed circuit
applications. It is particularly well suited for use in high-density
high-speed system applications. The 3DS16-325 is packaged in
a 64-pin PQFP .
