Abstract

The invention relates to a memory detection method and device, belongs to the technical field of memory detection, and solves the problem that the integrity check of a data packet cannot be met in theprior art. The memory detection method comprises the following steps: respectively packaging to-be-detected data in each memory region according to a one-to-one correspondence relationship between region labels in a database and each of data headers and data tails; sorting the to-be-tested data according to the region labels; when the missing memory area is detected, adding an empty memory blockwhich comprises empty data, a data head and a data tail; comparing the adjacent data tails with the data heads; and when the adjacent data tails are the same as the data heads, determining that the to-be-tested data is complete data. By comparing the adjacent data tails with the data heads, the to-be-tested data can be determined as complete data, so that the dependence on a hardware platform is reduced, and the integrity of data access is ensured.

Description

technical field [0001] The invention relates to the technical field of memory detection, in particular to a memory detection method and device. Background technique [0002] For users with high stability requirements, memory errors may cause fatal problems, and memory errors hinder the normal operation of the system. Memory errors are mainly the reading and writing of memory units, or a series of errors that occur when performing related memory operations, which is the root cause of most software disorders. Therefore, it is necessary to use memory detection technology to detect memory errors, especially in the embedded field, where safety and reliability are crucial. [0003] The implementation of common parity check and ECC check is all improved from the memory hardware. This method is simple and reliable, but it has higher requirements for the hardware; at the same time, the fault tolerance requirements of the memory are different, and the hardware structure will be diffe...
