Latest Patents

Hiroki Tanigami holds a patent for a semiconductor memory device with variable resistance elements. This device comprises a memory cell array that includes memory cells arranged in a matrix. Each memory cell features a selective transistor and a variable resistance element. The electric resistance of this element can be changed from a first state to a second state by applying a first write voltage. Conversely, it can revert from the second state to the first state by applying a second write voltage. Notably, the first write current for the initial writing operation is larger than the second write current for the subsequent operation. Additionally, the number of memory cells subjected to the second writing operation is greater than those subjected to the first operation, with at least the second memory cell number being plural. Hiroki Tanigami has 1 patent to his name.
