The invention discloses a smart phone storage system structure comprising: an application processing unit is connected with a RAW NAND FLASH device through a NAND FLASH bus for storing nonvolatile data and programs, and is connected with a DDR3L SDRAM device through a DDR bus for large-capacity High-speed data storage is connected to the baseband processing unit through the application of the baseband bridge bus, and the extended access to the PSRAM device is realized through the application of the baseband bridge bus; the application processing unit is also equipped with a RAW NAND FLASH controller to control the NAND FLASH bus and read Write data for encoding and decoding protection; the baseband processing unit is connected to the PSRAM device through the SRAM bus for small-capacity data storage space; the baseband processing unit is also provided with a clock management unit to control the switching of the mobile phone’s operating mode, the application processing unit clock, Turn on and off the DDR3L SDRAM device clock and NAND FLASH device clock. The invention also discloses an operation method of the smart phone storage system structure. The invention can reduce the production cost and operating power consumption of the smart phone.
Description
technical field [0001] The invention relates to the field of smart phones, in particular to a smart phone storage system. The invention also relates to the operation method of the smart phone storage system. Background technique [0002] With the development of semiconductor processing technology, people can integrate more semiconductor devices on the same wafer area to achieve more complex functions. The mobile phone has also evolved from a calling phone to a feature phone and then to a smart phone. [0003] A smart phone refers to a mobile phone that has an independent operating system and can be installed by the user by the software provided by a third-party service provider. The functions of the mobile phone can be continuously expanded through such programs, and the mobile phone can be connected to the wireless network through the mobile communication network. Smartphones need to support functions such as making calls, sending text messages, processing audio and video...
