Latest Patents

Among his latest innovations are two notable patents related to semiconductor memory devices. The first patent describes a semiconductor memory device that includes a writing circuit and a reading circuit. The writing circuit is designed to execute a setting action that converts the resistance of a variable resistance element to a low resistance by applying current from one end side to the other end side of a memory cell. It also includes a resetting action that converts the resistance to a high resistance by applying current in the opposite direction. The reading circuit performs two actions to read the resistance state of the variable resistance element, ensuring accurate data retrieval.

The second patent outlines a semiconductor memory device that features a memory cell array with multiple memory cells arranged in a matrix. Each memory cell is configured with a variable resistance element and a selection transistor connected in series. The set operation for a memory cell is performed by applying a set voltage pulse for a longer duration than that for a reset operation, while controlling the electric current to a certain low level using the selection transistor. This innovative approach allows for simultaneous application of the set voltage pulse to multiple memory cells, enhancing efficiency.
