MT28F322D20 General Description
The MT28F322D20 and MT28F322D18 are highperformance, high-density, nonvolatile Flash memory solutions that can significantly improve system performance. This new architecture features a two-memorybank configuration that supports dual-bank operation with no latency.
A high-performance bus interface allows a fast burst or page mode data transfer; a conventional asynchronous bus interface is provided as well.
The devices allow soft protection for blocks, as readonly, by configuring soft protection registers with dedicated command sequences. For security purposes, two 64-bit chip protection registers are provided.
The embedded WORD WRITE and BLOCK ERASE functions are fully automated by an on-chip write state machine (WSM). Two on-chip status registers, one for each of the two memory partitions, can be used to monitor the WSM status and to determine the progress of the program/erase task.
The erase/program suspend functionality allows compatibility with existing EEPROM emulation software packages.
The devices are manufactured using 0.18m process technology.
