  • Publication number: 20190385668
    Abstract: A dynamic random access memory (DRAM) and an operation method thereof are provided. The DRAM includes a temperature sensor, a dynamic memory cell array, a control circuit, a plurality of power supply circuits and a power control circuit. The temperature sensor senses an operating temperature of the DRAM. The control circuit is coupled to a dynamic memory cell array, and accesses and manages the dynamic memory cell array. The power supply circuits powers the dynamic memory cell array and the control circuit. The power control circuit controls power outputs of the power supply circuits. When the DRAM enters the self-refresh mode, the power control circuit selectively switches between a low power control state and a normal power control state according to the operating temperature of the DRAM.

  • Publication number: 20190237123
    Abstract: In a control method, external data input to the pseudo static random access memory with a reference clock signal in a write operation are counted to generate a first count value. Data written to a dynamic memory array of the pseudo static random access memory with a built-in clock signal in the write operation are counted to generate a second count value. An initial cycle of the built-in clock signal is smaller than a cycle of the reference clock signal. The first count value is compared with the second count value. When the first count value is equal to the second count value, a write match signal is enabled. When the enabled write match signal is received, the write operation is converted from an asynchronous mode to a synchronous mode to adjust the cycle of the built-in clock signal to be equal to the cycle of the reference clock signal.
