The MB85AS4MT offers an SPI-interface and operates with a wide range of power supply voltage, from 1.65V to 3.6V. It features an extremely small average current in read operations of 0.2mA at a maximum operating frequency of 5MHz. Fujitsu says it is aimed for battery operated wearable devices and medical devices such as hearing aids and IoT devices such as meters and sensors.

It's not clear what is the status of this chip, and whether it's already available for sampling or actual volume production. Here is the datasheet for the MB85AS4MT.
