STMicrolectronics claims to have developed a 4 Gb NAND flash capable of transmitting data at 36 MB/s. This rate, according to the company, is 50% better than the best results achieved to date. ST used an embedded error-correction processor that can detect and correct up to five errors per page employing a technique called BCH (Bose-Chaudhuri-Hocquenghem). The device was described at the International Solid State Circuits Conference (ISSCC).
