Spansion, the former flash arm of AMD, is making strides in SLC flash memory development. Having signed on Elpida as a development partner, the companies now claim to have created the world's first charge-trapping 4-Gigabit SLC NAND flash chip.
Charge-trapping is Spansion's own MirrorBit architecture developed for 40nm and smaller nodes, that features a simpler design and smaller die size. This makes for cheaper, higher-density chips and what the companies refer to as "superior performance, faster read and faster programming speeds".
After a first production round that turned out better than expected yields, the firms have come forward announcing their marketing plans for the kit. Elpida and Spansion plan to bundle these new NAND flash cells with Elpida's teeny Mobile RAM chips and bung them into just about anything they can get their hands on, ie: consumer electronics.
Currently, the memory is produced on 4Gb, 1.8V circuitry, but 1Gb and 2Gb kit, as well as a 3.0V range, will turn up to serve all market segments. First samples are going out to clients in the first quarter of 2011, say the companies, while mass production is expected just the following quarter.
Samsung, which had previously developed an identical technology dubbed Charge Trap Flash (CTF), is yet to announce plans for the technology.
