µPD44323362
32M-BIT CMOS SYNCHRONOUS FAST STATIC RAM
1M-WORD BY 36-BIT
HSTL INTERFACE / REGISTER-REGISTER / LATE WRITE
Description
The µPD44323362 is a 1,048,576 words by 36 bits synchronous static RAM fabricated with advanced CMOS
technology using Full-CMOS six-transistor memory cell.
The µPD44323362 is suitable for applications which require high-speed, low voltage, high-density memory and wide
bit configuration, such as cache and buffer memory.
The µPD44323362 is packaged in a 119-pin PLASTIC BGA (Ball Grid Array).
