Some deucedly hot properties are being described at this week’s International Solid State Circuits Conference in New York, and ones rounded up by Electronic News include DEC with a 32-bit microprocessor with 1Kb of on-chip data and instruction cache and a 28-entry translation buffer; AT&T with a 32-bit RISC having 13Kb of on-chip cache; Hitachi with a mainframe chip set in 1.3 micron CMOS with a 60nS cycle; Fujitsu with a 64K ECL static RAM having a blinding 5nS access time, and Hitachi with an ECL-compatible 1.3 micron CMOS 64K static with a 7nS access time, both arranged as 8K by 8 bits; Fujitsu with a complete CMOS cache including 49K of static RAM and cache logic, with a 19nS access time; IBM with a 256K static in nanoscopic 0.7 micron CMOS with its own on-chip power supply; and Sony and Hitachi both with 1M-bit statics arranged 128 by 8, Sony’s having a 32nS and Hitachi 42nS access time.
