Device and method for converging erased flash memories

摘要

A device for converging an erased flash memory array. The memory array includes a plurality of memory cells, each memory cell having a control gate, a floating gate, a source, and a drain. The drain voltage supply is coupled to the drain for providing a positive drain voltage. The constant current supply is coupled to the source for providing a source current. The control gate power supply is coupled to the control gate for providing a gradually increasing gate voltage to the control gate to control the source current flowing through the memory cell and adjust the threshold voltage of the memory cells.
