Memory data processing system and method

Abstract

The invention discloses a memory data processing system. The memory data processing system comprises a first memory, a second memory, a processor and a controller, wherein the first memory is a nonvolatile memory, the second memory is a volatile memory, initialization is conducted on the first memory and the second memory when the memory data processing system starts, the processor is used for conducting reading and writing on the first memory and the second memory, and the speed of conducting reading and writing on the first memory by the processor is lower than the speed of conducting reading and writing on the second memory by the processor. The controller is used for detecting whether the initialization of the first memory and the initialization of the second memory are completed or not, and when the initialization of the first memory and the initialization of the second memory are completed, the controller controls the processor to write data in the first memory into the second memory; the controller is further used for detecting whether the processor generates a read request command and controlling the data processor to read corresponding data from the second memory when the read request command is detected. In addition, the invention further provides a memory data processing method.

Description

technical field [0001] The invention relates to a memory data processing system and method. Background technique [0002] Data memory can be divided into volatile memory and non-volatile memory. Some data that needs to be stored permanently requires the use of non-volatile memory, for example, electrically erasable read-only memory (EEPROM). However, the microprocessor system reads and writes EEPROM at a slow speed, and it takes a long time to read a section of data. Therefore, when the amount of data read from the EEPROM is large, other events are likely to enter a long-time waiting state, causing the microprocessor system to freeze or other abnormal phenomena. Contents of the invention [0003] In view of this, it is necessary to provide a memory data processing system that is not easy to lose data and can read data quickly. [0004] In addition, it is also necessary to provide a data processing method for a memory that is not easy to lose data and can read data quick...

Problems solved by technology

However, the microprocessor system reads and writes EEPROM slowly, and it takes a long time to read a piece of data.

Therefore, when the amount of data read from the EEPROM is large, other events are likely to enter a long-term waiting state and cause the microprocessor system to freeze or other abnormal phenomena
