Toshiba’s embedded NAND Flash memories for mobile phones

Toshiba today announced a new series of embedded NAND Flash memories for mobile phones offering both a configurable single-level cell (SLC) memory area and a multi-level cell (MLC) memory area, allowing applications and data to be stored on the same chip. More and more mobile phones integrate a high resolution camera and audio player. They rely on high density memory to store images and music, as well to store boot program and log data for the mobile phone system. Toshiba’s new memories meet these demands in a novel solution that also reduces development burdens on manufacturers.

The five memories in the mobileLBA-NAND series range in capacity from 2- to 32-gigabits (GB). The 2 GB, 4 GB and 8 GB versions can be allocated as SLC up to their full capacity, while the 16 GB and 32 GB versions can support up to 8 GB of SLC, offering manufacturers greater flexibility in allocating memory in their products. Samples of mobileLBA-NAND packaged in MCPs will be available from August 2007. The new Toshiba NAND flash memories will be shipped primarily in MCPs, with a Fine Pitch Ball Grid Array (FBGA).
