Toshiba Develops World's Highest-Bandwidth, Highest Density Non-volatile RAM
Tuesday, 17. February 2009, 09:17:11
Toshiba Corporation today announced the prototype of a new FeRAM -- Ferroelectric Random Access Memory -- that redefines industry benchmarks for density and operating speed. The new chip realizes storage of 128-megabits and read and write speeds of 1.6-gigabytes a second, the most advanced combination of performance and density yet achieved. Full details of the new FeRAM was presented at the International Solid-State Circuits Conference 2009 (ISSCC2009) in San Francisco, USA.
The new FeRAM modifies Toshiba's original chainFeRAMTM architecture, which significantly contributes to chip scaling, with a new architecture that prevents cell signal degradation, the usual tradeoff from chip scaling. The combination realizes an upscaled FeRAM with a density of 128-megabit. Furthermore, a new circuit that predicts and controls the fluctuations of power supply supports high-speed data transfers. This allowed integration of DDR2 interface to maximize data transfers at a high throughput at low power consumption, realizing read and write speeds of 1.6 gigabytes a second. In developing the new FeRAM, Toshiba broke its own record of 32-megabit density and 200-megabit data transfers, pushing performance to eight times faster than the transfer rate and density of the previous records and the fastest speed of any non-volatile RAM.
