IM Flash is manufacturing 32G byte NAND chips the size of a thumbnail with its 34nm technology, and expects the chips to be used in small solid-state drives (SSDs) or flash memory cards aimed at products including digital cameras, digital camcorders and personal music players.

The 32G byte chips are multi-level cell (MLC) chips, which means they can handle more rewrites than the single level cell (SLC) variety of NAND flash.

Samsung Electronics, the world's largest NAND flash memory chip maker, is currently upgrading its chip factories to use 42nm technology and plans to start 30nm production next year.

The company showed off a multi-level cell 64G byte NAND flash memory chip made using 30nm manufacturing technology last year.
