Korea Inc may have just completed design of a 4M-bit memory chip (CI No 866), but Matsushita Electric, Toshiba Corp, and Hitachi Ltd have jointly gone four times better: they say they have completed development of 16M-bit memory chips – that’s 2M-bytes on a single chip – and will describe their designs at the International Solid State Circuit Conferences which opens in San Francisco on Wednesday. Nippon Telegraph & Telephone announced design of a 16M-bit part a year ago. While Siemens is just ramping up production of 1M-bit parts, Japanese manufacturers are beginning to put out samples of 4M-bit dynamics. Hitachi is believed to be using a stack configuration to piggyback the memory cells onto the chip.
