Memory device, memory system having memory device, and method of operating memory device

Abstract

A memory device includes a memory cell array including a plurality of memory blocks; a peripheral circuit configured to sequentially perform a channel initialization operation and a read operation on a memory block selected from among the plurality of memory blocks; and control logic configured to control the peripheral circuit to perform the channel initialization operation and the read operation, wherein the control logic sets a time during which the channel initialization operation is to be performed as channel initialization period depending on a potential level of supply voltage, the channel initialization operation being performed to remove hot holes in a channel of the selected memory block.
