The invention provides a memory access operation information recording method and device. The method comprises the following steps of: recording a memory access operation between a processor and a memory in a target operation process, so as to form memory access sequence information of the target operation process, wherein each piece of memory access operation information in the memory access sequence information comprises a memory access type, a memory access address and memory access data; and determining a termination storage state of the memory in the target operation process according tothe memory access sequence information of the target operation process. According to the method and device, the termination storage state of the memory in the target operation process can be obtainedby using fewer storage resources, so that the hardware overhead is reduced.
