1. A semiconductor device comprising:
a central processing unit that executes a command; a memory disposed in a memory space of the central processing unit and coupled to receive a control signal from the central processing unit, the memory including:
a first memory module,a second memory module,a third memory module, anda fourth memory module,each memory modules having a memory cell array including memory cells and a peripheral circuit that performs reading and writing data to or from the memory cells,each memory modules having a standby mode to consume less electric power than in a normal operation mode in which reading or writing to or from the memory cells is performed; a first control signal line coupled to the first memory module and the second memory module to transmit the control signal for controlling the normal operation mode and the standby mode in parallel to the first memory module and the second memory module; and a second control signal line coupled to the third memory module and the fourth memory module to transmit the control signal to the third memory module and the fourth memory module via the first memory module, wherein the first memory module has a greater number of memory cells than the second memory module. |
