A 30 ns 256 Mb DRAM with multi-divided array structure
A 256-Mb DRAM (dynamic random-access memory) fabricated using 0.25- mu m CMOS technology is described. The DRAM has 16-b I/Os, 30-ns access time, and 35-mA operating current for 60-ns cycle time. Key circuits include a partial cell array activation scheme in a multidivided array structure with a dua...

description | A 256-Mb DRAM (dynamic random-access memory) fabricated using 0.25- mu m CMOS technology is described. The DRAM has 16-b I/Os, 30-ns access time, and 35-mA operating current for 60-ns cycle time. Key circuits include a partial cell array activation scheme in a multidivided array structure with a dual word-line format for reducing power-line voltage bounce and operating current, a selective pull-up data-line architecture to increase I/O (input/output) width and to reduce current, and a time-sharing refresh to maintain a conventional refresh period without increasing power-line voltage bounce.< > |
