1.0 Description

SmartMedia 128MByte Product Manual

The SanDisk SmartMedia Card is a 3.3-V 1-Gbit (1,107,296,256) NAND Electrically Erasable and Programmable Read-Only Memory (NAND E

2

PROM) device, organized as 528 bytes X 32 pages X 8192 blocks. This 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).

The SanDisk SmartMedia Card is a serial-type memory device which uses the I/O pins for both address and data input and output as well as for command inputs. The Erase and Program operations are automatically executed making the device ideal for applications such as solid-state file storage, voice recording, image storage for digital cameras and other systems which require high-density non-volatile memory data storage.
