Abstract:
Provided herein is a semiconductor memory device exhibiting improved operating speed and a method of operating the semiconductor memory device. The semiconductor memory device may include a memory cell array, a peripheral circuit, and a control logic. The memory cell array may include a plurality of memory blocks. The peripheral circuit may perform a read operation on the memory cell array. The control logic may control an operation of the peripheral circuit. The control logic may control the peripheral circuit to perform a repair column masking operation on a selected memory block of the plurality of memory blocks, perform a first test operation on first drain select transistors included in the selected memory block, perform the first test operation on second drain select transistors different from the first drain select transistors while a result of the repair column masking operation remains.

Claim (Index 6):
The method according to  claim 5 , wherein the performing of the second test operation on the first drain select transistors comprises:\n applying a left reference voltage to the first drain select line; and determining drain select transistors each having a threshold voltage lower than the left reference voltage among the first drain select transistors by performing the CSC check operation.
