Abstract
A phase changeable random access memory (PRAM) and methods for manufacturing the same. An example unit cell of a non-volatile memory, such as a PRAM, includes a MOS transistor, connected to an address line and a data line, where the MOS transistor receives a voltage from the data line. The unit cell further includes a phase change material for changing phase depending on heat generated by the voltage and a top electrode, connected to a substantially ground voltage.
