PCRAM
PCRAM stands for Phase-Change Random-Access Memory. It is a type of non-volatile random-access memory that stores data by changing the physical state of a phase-change alloy, typically a chalcogenide glass. This material can be switched between two distinct states: amorphous (disordered) and crystalline (ordered). These two states have different electrical resistance properties, allowing them to represent the binary digits 0 and 1.
The operation of a PCRAM cell involves applying an electrical current to a heating element. A higher
PCRAM offers several advantages, including non-volatility, meaning data is retained even when power is off, and
