128 MB Smartmedia Flash Card (SSFDC)

Smart Media is a 128MB (134,217,728)x8bit NAND Flash Memory with a spare 4.096K(4,194,304)x8bit. Its 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 200ms and an erase operation can be performed in typically 2ms on a 16K-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 functions including pulse repetition, where required, and internal verify and margining of data. Even the write-intensive systems can take advantage of the SmartMedia's extended reliability of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm. The SmartMedia is an optimum solution for large nonvolatile storage applications such as solid state file storage, digital voice recorder, digital still camera and other portable applications requiring non-volatility.
