<p>The present invention relates to a voltage control circuit, semiconductor memory device, and method of controlling a voltage in a phase-change memory, wherein the voltage control circuit generates a controlled voltage which can be above the logic supply voltage. This voltage can limit the bit line voltage in a phase-change memory to allow the use of smaller transistors in the memory cells and in the program current part of the circuit. This results in smaller memory cells and modules.</p> |
