Abstract:
A resistive memory includes an array area where memory cells are arranged in rows and columns, word lines connected to the memory cells in a row direction, a local bit line extending in a column direction, local source lines, a shared bit line, and a writing device. Each memory cell includes a variable resistance element and an accessing transistor. The local source lines extend in the column direction and are connected to first electrodes of the memory cells in the column direction. The shared bit line is connected to the local bit line and second electrodes of the memory cells in the row direction. The writing device pre-charges the bit line and the source lines to a first voltage and applies a write pulse to the selected memory cell by discharging the corresponding selected source line after applying a write voltage to the selected word line, the writing device.
