Flash memory controller and data reading method

A flash memory controller for controlling a flash memory, wherein the flash memory comprises a first chip-enable-signal controlled area, the flash memory controller comprises:

• a control logic circuit coupled to the first chip-enable-signal controlled area of the flash memory through at least one channel to transmit data and commands;
• and
• a processor coupled to the control logic circuit to access the first chip-enable-signal controlled area on the channel through the control logic circuit, wherein the processor controls the control logic circuit to transmit a read command sequence to the first chip-enable-signal controlled area through the channel;
• and
• wherein the read command sequence comprises a first command and a second command, the first command is configured to instruct the first chip-enable-signal controlled area to read stored data and read operating temperature information, and in response to the transmission of the second command, the processor controls the control logic circuit to receive at least one of the stored data and the operating temperature information from the first chip-enable-signal controlled area.
