Product Summary

The KM29W040AT is a 512Kx8bit NAND flash memory. Its NAND cell structure provides the most cost-effective solution for digital audio recording. A program operation programs a 32-byte frame in typically 500ms and an erase operation erase a 4K-byte block in typically 6ms. Data in a frame can be read out at a burst cycle rate of 120ns/byte. The I/O pins serve as the ports for address and data input/output as well as for command inputs. The on-chip write controller automates the program and erase operations, including program or erase pulse repetition where required, and performs internal verification of cell data.
