Abstract

A memory device includes bitlines, wordlines and a matrix of memory cells arranged in rows and columns. Each of the bitlines is electrically connected to memory cells in one of the columns. Each of the wordlines is electrically connected to memory cells in one of the rows. A bitline write voltage is applied to a first bitline. A wordline voltage is applied to a first wordline for writing data to a first memory cell connected to the first wordline and the first bitline. The first bitline and the second bitline are electrically connected for charge sharing between the first bitline and the second bitline. A predetermined time after electrically connecting the first bitline and the second bitline, the first and the second bitline are electrically disconnected and the bitline write voltage is applied to the second bitline. The wordline voltage is applied to a second wordline for writing data to a second memory cell connected to the second wordline and the second bitline.
