Abstract
A semiconductor memory device is provided. The semiconductor memory device includes a memory cell array, a read only memory (ROM), a central processing unit, and a random access memory (RAM). The memory cell array stores data related to operating conditions of the semiconductor memory device. The ROM stores data used to control an operation of the semiconductor memory device. The central processing unit controls the operation of the semiconductor memory device according to the data read from the ROM. The central processing unit reads the data related to the operating conditions from the memory cell array in response to a requested operation and then temporarily stores the read data related to the operating conditions in the RAM. The central processing unit further reads the data related to the data related to the operating conditions from the RAM for controlling the operation of the semiconductor memory device.
