Toshiba ontwikkelt ‘s werelds eerste NAND-flashgeheugen uit 16 siliciumplaatjes met TSV-technologie

TOKYO–(BUSINESS WIRE)– Toshiba Corporation heeft vandaag bekendgemaakt dat het ‘s werelds eerste NAND-flashgeheugen gaat maken met gebruik van de technologie Through Silicon Via (TSV). Een prototype van het flashgeheugen, dat bestaat uit zestien op elkaar gestapelde blokjes geleidend materiaal, zal voor het eerst te zien zijn op de Flash Memory Summit 2015, die van 11 tot 13 augustus plaatsvindt in Santa Clara in de Verenigde Staten.

Momenteel worden NAND-flashgeheugens uit opgestapelde plaatjes bijeen gehouden door draad. TSV maakt daarentegen gebruik van verticale elektroden en via’s die door het silicium van de blokjes gaan en deze bijeen houden. Dit maakt zeer snelle invoer en uitvoer van gegevens mogelijk en vermindert het energieverbruik.

Toshiba Develops World’s First 16-die Stacked NAND Flash Memory with TSV Technology

TOKYO–(BUSINESS WIRE)– Toshiba Corporation (TOKYO:6502) today announced the development of the world’s first *1 16-die (max.) stacked NAND flash memory utilizing Through Silicon Via (TSV) technology. The prototype will be shown at Flash Memory Summit 2015, to be held from August 11 to 13 in Santa Clara, USA.

The prior art of stacked NAND flash memories are connected together with wire bonding in a package. TSV technology instead utilizes the vertical electrodes and vias to pass through the silicon dies for the connection. This enables high speed data input and output, and reduces power consumption.

Toshiba’s TSV technology achieves an I/O data rate of over 1Gbps which is higher than any other NAND flash memories with a low voltage supply: 1.8V to the core circuits and 1.2V to the I/O circuits and approximately 50% *2 power reduction of write operations, read operations, and I/O data transfers.

This new NAND flash memory provides the ideal solution for low latency, high bandwidth and high IOPS/Watt in flash storage applications, including high-end enterprise SSD.

A part of this applied technology was developed by the New Energy and Industrial Technology Development Organization (NEDO).
