Micron Technology announced sample availability of a new 64Mb high-performance Flash memory device, MT28F644W18, developed specifically for mobile applications. This 1.8V core Flash memory device supports an input/output voltage of 1.8V, and is the fastest high-density Flash memory presently available in the market.
Micron’s new Flash memory architecture provides additional enhanced performance feature sets, such as, a flexible 4Mb multi-partitioned architecture, clock suspend, and fast programming algorithm to meet performance demands for emerging mobile platforms. The multi-partitioned architecture allows for more partitions and supports code segmentation for different applications, yielding improved efficiency. Micron’s Flash Data Management (MFDM) software manages operations and optimizes performance in this multi-bank architecture. The clock suspend feature allows suspension of a burst sequence for the retrieval of data from another device on the same bus while still allowing the burst sequence to resume at a later time with zero initial access latency penalty. The fast programming algorithm feature enables fast data-stream programming (3.1µs/word typ.) when the in-factory voltage is set to 12V (Vpp=12V). The same fast data-stream programming at an in-system voltage of 1.8V (Vpp=1.8V) makes programming and assembly easier.
This 64Mb device is organized as 4Mb x 16 and available in a FBGA package. Micron’s mobile product family also consists of other low power Flash memory devices available in 32, 64 and 128Mb configurations.
