Datasheet Summary
TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
256-MBIT (32M × 8 BITS) CMOS NAND E PROM DESCRIPTION
The TC58256A is a single 3.3 V 256-Mbit (276,824,064) bit NAND Electrically Erasable and Programmable Read-Only Memory (NAND E2PROM) organized as 528 bytes × 32 pages × 2048 blocks. The device has a 528-byte static register which allows program and read data to be transferred between the register and the memory cell array in 528-byte increments. The Erase operation is implemented in a single block unit (16 Kbytes + 512 bytes: 528 bytes × 32 pages). The TC58256A is a serial-type memory device which utilizes the I/O pins for both address and data input/output...
