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 E

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
麓
32 pages).
The TC58256A is a serial-type memory device which utilizes the I/O pins for both address and data input/output
as well as for command inputs. The Erase and Program operations are automatically executed making the device
most suitable for applications such as solid-state file storage, voice recording, image file memory for still cameras
and other systems which require high-density non-volatile memory data storage.
