  • Publication number: 20240133751
    Abstract: Disclosure regards a temperature sensor and a temperature-sensing data processing module, including two counting units, each configured to set a reference clock signal and a frequency conversion signal to be a counting-clock signal and a counting-sample signal according to a control signal, wherein during a sampling period consisting of at least one signal cycle of the counting-sample signal, the two counting units count the numbers of rising edges and falling edges of the counting-clock signal; and a count-control unit configured to generate a doubled-frequency counting value based on a sum of the number of rising edges and the number of falling edges to generate a temperature value based on the doubled-frequency counting value and a temperature-frequency fitting function. Therefore, problems regarding temperature estimation errors in the prior art are effectively solved.

  • Patent number: 11521689
    Abstract: A non-volatile memory includes a plurality of blocks and a controller. Each of the plurality of blocks includes a plurality of pages, and each of the plurality of pages includes a plurality of storage units. The controller is configured to perform: receiving an erase command for a target block of the plurality of blocks; executing a read operation on each page of the target block; and executing a first erase operation to apply word line voltages to the plurality of pages, where the word line voltages are determined by a read result of the read operation of each page. An operation method of a non-volatile memory and an electronic device are also provided.
