SEMICONDUCTOR MEMORY DEVICE
摘要:
According to one embodiment, a semiconductor memory device performs writing of data to a semiconductor memory element in response to a request to write the data with a specified logical block address from a host and performs writing of valid data to the semiconductor memory element for compaction according to a log-structured method. The semiconductor memory device adjusts a frequency of the writing response to a request from the host and a frequency of the writing for compaction according to a predetermined ratio.
