NEC Corp and Ascii Corp have jointly developed a 256K-bit Triple Port Buffer memory chip for use with graphics processors: the uPD42232CU, which will be on sale from July, combines 32K 8-bit words of dynamic memory, and 128 8-bit data registers, with functions for simultaneous control of three serial ports – a plain access port for writing graphics data, a pixel access port for rewriting or reading data, plus a multiple graphic data control port; access time on the first two ports is 220nS; NEC offers the part in two versions, a random access version for $35 and a serial access version for $28, and is planning to manufacture 300,000 a month.
