Abstract
The present application discloses a serial flash memory, including a memory array, a row decoder, a column decoder, a control module, and an SPI interface, wherein the control module includes a row enable signal; and when the last bit of an SPI row address in an SPI address signal is to be read, the control module enables the row enable signal, and the row enable signal enables an internal row address of an internal address of the serial flash memory to be valid and enables the row decoder to perform decoding and select the internal row address. The present application further provides an address control method of a serial flash memory. In the present application, the timing requirement on the row address can be relaxed, the area of the row decoder can be reduced, and the area of the row drive circuit can be reduced.
