This new product is anon-volatile memoryhaving a large memory density of 12Mbit in a very small package size of approximately 2mm x 3mm. It has an outstandingly low level of read current of 0.15mA on average during read operations. Therefore, battery consumption can be minimized by mounting the MB85AS12MT in battery-operated devices with frequent data-read operations.

With features of small package size and small read current, this product is ideal for use in wearable devices such as hearing aids and smart watches.

The MB85AS12MT operates at a wide range of power supply voltage from 1.6V to 3.6V. The new ReRAM product’s memory density is 1.5 times larger than the existing 8Mbit ReRAM while keeping the same package size, WL-CSP (Wafer Level Chip Size Package), with the same pin assignment. The product can store character data for approximately 90 pages of newspaper in a small package size.

TheWL-CSPused for the MB85AS12MT can save approximately 80% of its mounted surface area compared with 8-pin SOP that is frequently used for memory devices with the Serial Peripheral Interface (SPI).
