Intelligent cell phone storage system structure and operating method thereof

Abstract

The invention discloses an intelligent cell phone storage system structure which comprises that an application processing unit is connected with a RAW, NAND and FLAS component by an NAND and FLASH bus and used for storing non-volatile data and procedures. The application processing unit is connected with a DDR 3L and SDRAM component by a DDR bus and used for storing of high-volume high-speed data. The application processing unit is connected with a baseband processing unit by an application baseband bridge bus and achieves expansion access to a PSRAM component by the application baseband bridge bus. The application processing unit is also provided with a RAW, NANA and FLASH controller which is used for controlling the NANA FLASH bus and conducts coder and decoder protection on read-write data. The baseband processing unit is connected with the PSRAM component by the SRAM bus and used for small-volume data storage space. The baseband processing unit is also provided with a clock management unit and used for controlling opening and closing of an application processing unit clock, a DDR3L and SDRAM component clock and NAND and FLASH component clock when an operating mode of a cell phone is switched. The invention further discloses an operating method of the intelligent cell phone storage system structure. The operating method of the intelligent cell phone storage system structure can reduce production cost and operating consumption of an intelligent cell phone.

Description

technical field [0001] The invention relates to the field of smart phones, in particular to a smart phone storage system structure. The invention also relates to the operation method of the smart phone storage structure. 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 au...
