It's interesting that this article highlights a significant limitation of ReRAM: limited endurance (limited number of ‘1’/’0’ write cycles)

Fujitsu's ReRam product has unlimited reads but only 1 million guaranteed writes and is recommended for applications that only write data very infrequently. They are targetting wearable devices and hearing aids.

Fujitsu Semiconductor Memory Solution announced the release of the 8Mbit ReRAM(*1) MB85AS8MT, which has the world's largest density as a mass-produced ReRAM product, available from September 2019. This ReRAM product was jointly developed with Nuvoton Technology Corporation Japan (former Panasonic Semiconductor Solutions Co., Ltd)(*2).The MB85AS8MT is an EEPROM-compatible non-volatile memory with SPI-interface that operates with a wide range of power supply voltages from 1.6V to 3.6V. One major feature of this memory is an extremely small average current for read operations of 0.15mA at an operating frequency of 5MHz. This enables minimal battery consumption when mounted in battery-operated applications with frequent data-read operations.Since it can be provided in a very small WL-CSP (Wafer Level Chip Size Package), it is optimal for battery-operated small wearable devices such as hearing aids, smart watches, and smart band.

It will be interesting to find out if Weebit's ReRAM is also limited in terms of write counts and therefore limited in applications it is suited to. Or have they found a novel way to overcome this typical weakness in the tech?
