Flash Integrates Management Functions

To simplify system designs and improve product performance, the HN29V256A series 256-Mb superAND flash memory devices integrate four on-chip memory management functions, eliminating the need for external circuits. A bad-sector management function promises reliable operation throughout the chip's lifetime, regardless of whether a defect is present when the device is shipped or occurs after shipment. The wear-leveling function makes effective use of flash memory rewrite areas and extends the life of the device. An error-correction function improves data reliability and decreases the workload on the system side, while a power-on auto-read (boot) function allows data to be read from an expanded 8 KB area without a command or address input. The series consists of two devices: HN29V256A0B that supports a 16-bit bus width and HN29V256A1B supporting an 8-bit bus width. Both come in a 10 mm x 11.5 mm x 1.2 mm CSP and are priced at $11 each/10K. For more information, call Akiko Ishiyama at RENESAS TECHNOLOGY AMERICA INC., San Jose, CA. (408) 382-7407.
