A system and method for quickly and efficiently programming hard-to-program storage elements in non-volatile integrated memory devices is presented. A number of storage elements are simultaneously subjected to a programming process with the current flowing through the storage elements limited to a first level. As a portion of these storage elements reach a prescribed state, they are removed from the set of cells being programmed and the current limit on the elements that continue to be programmed is raised. The current level in these hard-to-program cells can be raised to a second, higher limit or unregulated. According to another aspect, during a program operation the current limit allowed for a cell depends upon the target state to which it is to be programmed.
A non-volatile memory comprising:
In a non-volatile memory including an array of multi-state storage elements connected in one or more columns along bit lines and along one or more rows connected to word lines, a method of programming one or more selected storage elements along a first word line each to a corresponding target one of said multi-states during a programming process, comprising:
