The TC58128A is a single 3.3 V 128-Mbit (138,412,032) bit NAND Electrically Erasable and Programmable Read-Only Memory (NAND E2PROM) organized as 528 bytes x 32 pages x 1024 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 x 32 pages).
