Abstract
A semiconductor memory device includes a memory cell array, an error correction circuit and a control logic circuit. The error correction circuit performs an error correction code (ECC) encoding on write data to be stored in the memory cell array, and performs an ECC decoding on read data from the memory cell array. The control logic circuit controls access to the memory cell array and generates an engine configuration selection signal based on a command. The error correction circuit reconfigures a number of units for which ECC including the ECC encoding and the ECC decoding is performed, in response to the engine configuration selection signal.
