摘要
A crossbar array apparatus suppressing deterioration of write precision due to a sneak current is provided. A synapse array apparatus includes a crossbar array configured by connecting resistance-variable type memory elements, a row selecting/driving circuit, a column selecting/driving circuit, and a writing unit performing a write operation to a selected resistance-variable type memory element. The writing unit measures the sneak current generated when applying a write voltage to a selected row line before applying the write voltage, and then the writing unit performs the write operation to the selected resistance-variable type memory element by applying a write voltage having a sum of the measured sneak current and a current generated for performing the write operation.
