RAM-transformed logic builds on a no-batteries foundation

摘要

An increasing percentage of the program-mable-logic industry's players are turning to SRAM-based process technologies to build their latest products (see "Lithography advancements 'axcelerate' antifuse lineage," EDN, July 11, 2002, pg 22). In FPGAs, this trend has historical underpinnings: Aside from a brief antifuse experiment, market leader Xilinx (www.xilinx.com) has always built its chips on SRAM processes, and No. 2, Altera (www.altera.com), has exclusively relied on SRAM for successive generations of its Acex, Apex, Flex, Mercury, newest Stratix, and ARM-inclusive Excalibur parts.
