Abstract:
Structures and methods for a multi-bit phase change memory are disclosed herein. A method includes establishing a write-reference voltage that incrementally ramps over a write period. The increments of the write-reference voltage correspond to discrete resistance states of a storage cell of the multi-bit phase change memory.

Claim (Index 1):
A phase change memory system comprising a read head which includes a sense comparator having multiple inputs and an output,\n wherein:\n the sense comparator is configured to change logic states from a high logic state to a low logic state when a first input and a second input which is connected to a storage cell are a same value or substantially the same value, \n the storage cell is associated with a bit line, a word line, a master bit line and a column decoder, \n the column decoder selectively connects the storage cell and the bit line to the master bit line via transistor, \n the storage cell is selected for reading by the bit line, the word line and the column decoder such that a voltage corresponding to a value of the storage cell is produced on the master bit line, \n the first input of the sense comparator receives a read-reference voltage which is generated by a controllable current source, \n the read-reference voltage is ramped in different time increments having a respective voltage level that corresponds to different resistance states of a storage cell, and \n the discrete resistance state of the storage cell is a predefined value which represents a combination of data bits.
