Fujitsu introduces nonvolatile memory mb85as12mt with 12mbit storage density
2022-06-02
ReRAM resistive random access memory is a nonvolatile memory in which a pulse voltage is applied to a thin metal oxide film, resulting in a huge change in the resistance of recording 1 and 0. The simple structure of metal oxide is used between the electrodes, and the manufacturing process is very simple. At the same time, it still has the excellent characteristics of low power consumption and fast writing speed.
Mb85as12mt this new product is a nonvolatile memory with a large storage density of 12mbit and a package size of about 2mmx3mm. It has a very low reading current of 0.15MA on average during the reading operation. The product has the characteristics of small package size and low reading current, and is very suitable for wearable devices such as hearing aids and smart watches.
Mb85as12mt is a nonvolatile memory with 12mbit storage density, which can work in a wide power supply voltage range from 1.6V to 3.6V. The memory density of the new ReRAM product is 1.5 times that of the existing 8mbitreram, while maintaining the same package size WL-CSP (wafer level chip size package) and the same pin allocation. The product can store about 90 pages of newspaper character data in a small package size of about 2mmx3mm.
The WL-CSP used by mb85as12mt can save about 80% of the installation surface area compared with the 8-pin SOP often used for storage devices with serial peripheral interface (SPI).
Compared with other nonvolatile memories, the new ReRAM product has a very small read current level. At 5MHz operating frequency, the average reading current is as low as 0.15MA, and even at 10MHz, the maximum reading current is 1.0mA. Therefore, by installing the mb85as12mt in a battery powered device with frequent data reading operations, such as specific program reading or setting data reading, battery consumption can be minimized. It is very suitable for small battery powered wearable devices, such as hearing aids and smart watches.
While Fujitsu semiconductor memory solutions continue to seek higher density fram products for customer devices that need frequent data rewriting, they have been developing new nonvolatile memory to meet the requirements of frequent data reading, thus introducing this new 12mbit ReRAM product. Fujitsu semiconductor memory solutions continuously develop various low-power memory products to meet the needs of customers.
