By CBR Staff Writer

Toshiba Corp, which claims to have invented the flash EEPROM in 1987, has a new family of 256K-bit CMOS flash-erase EEPROMs, the TC 58257 AP/AF: its contents can be erased in less than a second and rewritten in four seconds, and it comes in three versions, with access times of 170nS, 200nS and 250nS, each organised as 32,000 by 8-bits; intended for storing frequently used programs in computer systems, the parts are sampling at around $47 for dual in-line packs, $50 for flat packs.
