Abstract
Provided is a memory device including a cell array, a peripheral circuit configured to control a memory operation of the plurality of memory cells, a test logic circuit configured to operate in a test mode and configured to perform a test operation on the plurality of memory cells, a first regulator configured to regulate a first power supply voltage received through a first pad and provide the first power supply voltage to at least one of the cell array and the peripheral circuit, and a power manager between the first pad and an input terminal of the first regulator, and between the first pad and the test logic circuit and configured to provide a test power supply voltage to the test logic circuit. In the test mode, while a first target voltage level of the first regulator fluctuates, a second target voltage level of the power manager is maintained constant.
