What isPCRAM

PCRAM, also known as PRAM, PCM, PCME, OUM, and C-RAM, is a type of nonvolatile random-access memory. It uses chalcogenide glass’s unique properties to store data.

This technology leverages heat generated by an electric current flowing through a heating element made of titanium nitride to either quickly heat and quench the glass, converting it to an amorphous state, or hold it in its crystallization temperature range for some time, converting it to a crystalline state. It can also maintain a number of distinct intermediary states, allowing it to hold multiple bits in a single cell.

While PCM is capable of holding multiple bits with a single cell, it is challenging to program cells in this way. As a result, this capability was not implemented in other similar technologies like flash memory.


What is the difference between PCRAM and flash memory?

PCRAM uses heat generated by electricity to quickly convert the glass to an amorphous or crystalline state, while flash memory uses an electric charge to move electrons within a storage medium to record data.

Is PCRAM a new technology?

PCRAM is not a new technology. It has existed since the 1960s, but it has not been used extensively in consumer electronics.

What are the benefits of using PCRAM?

PCRAM consumes less power than other flash memory technologies, reads and writes faster, and lasts longer.


PCRAM is a promising technology due to its ability to multitask and consume less power than other similar technologies. As this technology advances, we will likely see it implemented more widely in various consumer electronics.
