These assorted technologies have wide ranging applications across existing and emerging technology sectors. The advantage of the phase change technology is that the state remains intact when power is removed from the device, thereby making it a non-volatile form of storage. Circuitry around the cell then detects the change in resistance as the two states have a different resistance and as a result it detects whether a "1" or "0" is stored in that location. Abbreviated as PCM, phase change memory is a type of non-volatile memory that is much faster than the common flash memory, and it also uses up to one-half the power. Because it is much closer in speed to dynamic RAM (DRAM), phase change memory technology is ideal for both non-volatile dual in-line memory modules (NVDIMMs) and non-volatile memory express (NVMe) solid state drives (SSDs). Phototransistor     Resistive random-access memory is a type of non-volatile random-access computer memory that works by changing the resistance across a dielectric solid-state material, often referred to as a memristor.
