Product Summary
The KM29W32000AT is a 4M × 8bit NAND Flash Memory with a spare 128K × 8bit. The KM29W32000AT’s NAND cell provides the most cost-effective solution for the solid state mass storage market. A program operation programs the 528-byte page in typically 250ms and an erase operation can be performed in typically 2ms on an 8K-byte block. Data in the page can be read out at 50ns cycle time per byte. The I/O pins serve as the ports for address and data input/output as well as command inputs. The on-chip write controller automates all program and erase system functions, including pulse repetition, where required, and internal verify and margining of data.
