Abstract
A memory device includes: a memory cell array, multiple bit lines, a compensation circuit, a holding circuit, and a control logic circuit. The memory cell array includes multiple memory cells. Each of the bit lines is connected to at least one of the memory cells. Among the bit lines, a predetermined voltage is applied to selected bit lines connected to selected memory cells. The compensation circuit includes a sampling circuit that generates a sampling value by sensing a leakage current applied to non-selected memory cells from among the plurality of memory cells. The holding circuit compensates for a voltage applied to the selected bit lines, based on the sampling value. The control logic circuit outputs a sampling-enable signal that controls enabling of the sampling circuit and a holding-enable signal that controls enabling of the holding circuit.
