Abstract
A multi-bit NVM cell includes a storage unit having resistive elements, such as phase change resistive elements. The NVM cell may be configured as a single port or dual port multi-bit cell. The NVM cell includes a cell selector. The cell selector selects the multi-bit cell. When appropriate signals are applied to the NVM cell, the cell selector selects an appropriate resistive element of the storage unit. A plurality of storage units can be commonly coupled to the cell selector, facilitating high density applications.
