DATA SHEET MOS INTEGRATED CIRCUIT µPD4481162, 4481182, 4481322, 4481362 8M-BIT ZEROSBTM SRAM PIPELINED OPERATION Description The µPD4481162 is a 524,288-word by 16-bit, the µPD4481182 is a 524,288-word by 18-bit, the µPD4481322 is a 262,144-word by 32-bit and the µPD4481362 is a 262,144-word by 36-bit ZEROSB static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell. The µPD4481162, µPD4481182, µPD4481322 and µPD4481362 are optimized to eliminate dead cycles for read to write, or write to read transitions. These ZEROSB static RAMs integrate unique synchronous peripheral circuitry, 2-bit burst counter and output buffer as well as SRAM core. All input registers are controlled by a positive edge of the single clock input (CLK).
