Semiconductor device, electronic component, and electronic device

A semiconductor device comprising:

• a microcontroller unit comprising:
• a clock generator configured to generate a first clock signal and a second clock signal;
• a memory section comprising a memory cell, the memory section configured to generate a wait signal;
• and
• a processor core configured to delay access to the memory section on the basis of the wait signal,
• wherein the memory section comprises at least one of an SRAM, a flash memory, an ferroelectric RAM, a magnetoresistive RAM, a resistance RAM, and a phase change RAM,
• wherein a write cycle time of the memory cell is longer than a read cycle time of the memory cell, and
• wherein a first write cycle time of the memory cell when the microcontroller unit is operated by the first clock signal is longer than a second write cycle time of the memory cell when the microcontroller unit is operated by the second clock signal.
