A semiconductor memory apparatus includes a memory cell unit and an internal voltage stabilization apparatus. The memory cell unit includes a row decoder, a column decoder, and a memory cell array. The internal voltage stabilization apparatus includes an operation termination determination unit configured to determine whether an operation of the semiconductor memory apparatus is terminated on thebasis of an external input voltage and output an operation termination command, a termination voltage generation unit configured to generate a termination voltage having a preset voltage value on thebasis of a determination result of operation termination by the operation termination determination unit, and a switch unit. The switch unit includes a plurality of switches that are turned in response to the operation termination command, and supplies the termination voltage, input from the termination voltage generation unit, to a plurality of internal nodes of the memory cell array. 一种半导体存储装置，包括存储单元单位和内部电压稳定装置。存储单元单元包括行
