MirrorBit® Quad Technology

Expanding Flash Memory Innovation for Electronic Devices

As consumers use more data and content, Flash memory solutions are enabling a more mobile, digital, media-rich global society. Semiconductor companies are continually challenged to produce higher capacity storage at lower cost and with greater capabilities. Spansion is leading the charge, continuing innovation in non-volatile storage with the introduction of MirrorBit® Quad technology.

Spansion® MirrorBit Quad technology is designed to expand Flash memory innovation and lower the cost of storing significant amounts of digital content inside electronic devices. The technology will be the basis for a family of data storage solutions created for the integrated Flash memory market. Spansion also plans to partner with leading companies to bring digital media solutions to segments of the removable market.

How MirrorBit® Quad Technology Works

MirrorBit Quad technology, as with Spansion's two-bit-per-cell MirrorBit technology, stores charges in two distinct locations on a non-conducting nitride storage medium to deliver fundamental cost, quality and manufacturing advantages over floating-gate technology. While two-bit-per-cell MirrorBit technology stores one bit per storage location, MirrorBit Quad stores two bits per storage location.

MirrorBit Quad has the headroom to support even more bits-per-cell in the future. Due to the increased storage capacity per cell, MirrorBit Quad technology is capable of delivering up to 30 percent smaller effective cell size per bit than floating-gate MLC NAND Flash memory technology at the same process technology node. Production of MirrorBit Quad 512 Mb, 1 Gb, and 2 Gb products on 90nm is planned by year-end, followed by 1 Gb, 2 Gb, 4 Gb, 8 Gb and 16 Gb products on 65nm in 2007.
