Reducing programming time of a memory cell

摘要

The present invention provides methods and apparatus for adjusting voltages of bit and word lines to program a two terminal memory cell. The invention may include setting a first line connected to a memory cell to a first voltage from a first line standby voltage, charging a second line connected to the memory cell to a predetermined voltage from a second line standby voltage, and switching the first line from the first voltage to a second voltage. The voltage difference between the first voltage and the predetermined voltage is such that a safe voltage results that does not program the memory cell. A voltage difference between the second voltage and the predetermined voltage is such that a programming voltage operative to program the memory cell results.
