Multi-level memory cell utilizing measurement time delay as the characteristic parameter for level definition

摘要

A method for operating a memory cell. Memory cells represent binary values by storing a characteristic parameter. The method of memory cell operation entails receiving a binary value to be stored by a memory cell. A determining operation determines a target discharge time corresponding to the binary value. The target discharge time being the time needed to discharge a pre-charged circuit through the said memory cell to a predetermined level. A storing operation stores a characteristic parameter in the memory cell such that an electron discharge time through an electronic circuit formed, at least partially, by the memory cell, is substantially equal to the target discharge time.
