GENERAL DESCRIPTION
Offered in 512Mx8bit, the K9F4G08X0B is a 4G-bit NAND Flash Memory with spare 128M-bit. The device is offered in 2.7V and 3.3V Vcc. Its NAND cell provides the most cost-effective solution for the solid state application market. A program operation can be performed in typical 200µs on the (2K+64)Byte page and an erase operation can be performed in typical 1.5ms on a (128K+4K)Byte block. Data in the data register can be read out at 25ns cycle time per Byte. The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write controller automates all program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the write-intensive systems can take advantage of the K9F4G08X0B′s extended reliability of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mappingout algorithm. The K9F4G08X0B is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable applications requiring non-volatility.
