2 / 22 page  KM29W040AT, KM29W040AIT FLASH MEMORY 2 512K x 8 Bit NAND Flash Memory The KM29W040A 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 500 µs 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 com- mand inputs. The on-chip write controller automates the pro- gram and erase operations, including program or erase pulse repetition where required, and performs internal verification of cell data. The KM29W040A is an optimum solution for flash memory application that do not require the high performance levels or capacity of larger density flash memories. These application include data storage in digital Telephone Answering Devices(TAD) and other consumer applications that require voice data storage.
