摘要: A method for performing an erase operation is disclosed in a non-volatile memory having a plurality of memory cells. At least one memory cell is programmed having a threshold voltage level in a first region before programming, and after programming the memory cell has a threshold voltage level in a second region, wherein the second region is higher in threshold voltage than the fist region. The erasing operation implements a programming of memory bits that can inject negative charge carriers or electrons into a memory cell instead of using the conventional technique of injecting hot holes into the memory cell. This can avoid room temperature drift and charge loss caused by hot hole injection.

摘要: A method for determining read voltage margins in a memory array compares as-read sum codes generated from data read from the memory array with expected sum codes generated from the loaded data. The read voltage (Vt) is stepped and the as-read sum codes are compared to the expected sum codes to determine the Vt range(s) that provides matching sum codes. Multiple read voltage margins (i.e. the read voltage margins between multiple programming levels of the MLC memory array) are determined in a parallel fashion as Vt is stepped across its range.
