Fujitsu Semiconductor Memory Solution Limited has launched new 8Mbit FeRAM MB85R8M2TA with parallel interface, which is the first product to guarantee 100 trillion read/write cycle times in Fujitsu’s FeRAM product family. Evaluation samples are currently available.(Fig.1)

The new product achieves both high-speed operations, approximately 30% faster access speed, and low power consumption, 10% less operating current, compared to Fujitsu’s conventional products. This memory IC is an ideal replacement of SRAM in the industrial machines that require high-speed operation.(Fig.2)

Fig.2: Example of FeRAM Usage

FeRAM is a non-volatile memory product with superior features of high read/write endurance, fast writing speed operation and low power consumption, and it has been mass-produced for over 20 years.

Fujitsu has been providing 8Mbit FeRAM MB85R8M2T with parallel interface since June 2018. While promoting the product, the company heard voices of customer requirements such as guaranteed writing endurance of more than 10 trillion times, operation as fast as SRAM and TSOP package compatibility to SRAM. Fujitsu is now pleased to introduce its new 8Mbit FeRAM product satisfying these requirements, maintaining FeRAM’s unique feature of lower power consumption.

The MB85R8M2TA with an SRAM-compatible parallel interface operates at a wide range of power supply voltage from 1.8V to 3.6V. It is the first product that guarantees 100 trillion read/write cycle times in Fujitsu’s FeRAM product family.

Being capable of operating up to 25ns in fast page mode, the new FeRAM’s access speed is as high as SRAM at continuous data transfer. It achieves not only higher-speed operation but lower power consumption than Fujitsu’s conventional FeRAM product. This FeRAM has the maximum write current of 18mA, 10% less than the current product, and the maximum standby current of 150µA, 50% less.(Fig.3) It is housed in a 44-pin TSOP package which is the same package as Fujitsu’s 4Mbit FeRAM in addition to a 48-pin FBGA package.

Fig.3: Current Comparison

The new 8Mbit FeRAM brings customers the benefit of eliminating a data-backup battery necessary for SRAM in some cases. Fujitsu’s FeRAM product can solve the following issues arising from replacing SRAM with non-volatile memory.(Fig.4)
