Description
The µPD44325082 is a 4,194,304-word by 8-bit, the µPD44325092 is a 4,194,304-word by 9-bit, the µPD44325182 is a 2,097,152-word by 18-bit and the µPD44325362 is a 1,048,576-word by 36-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
Features
- 1.8 ± 0.1 V power supply and HSTL I/O.
- DLL circuitry for wide output data valid window and future frequency scaling.
- Separate independent read and write data ports with concurrent transactions.
- 100% bus utilization DDR READ and WRITE operation.
- Two-tick burst for low DDR transaction size.
- Two input clocks (K and /K) for precise DDR timing at clock rising edges only.
- Two output clocks (C and /C) for precise flight time and clock skew.
