擦除块读请求处理方法与装置

提供了擦除块读请求处理方法与装置。所公开的处理IO请求的方法，包括：响应于收到第一读请求，访问第一读请求对应的第一FTL表项，获取第一FTL表项记录的第一物理地址；若包含第一物理地址的物理块处于擦除状态，重放所述第一读请求。 The invention provides a processing method and device for accessing a read request of an erase block. The method comprises the following steps: in response to receiving a first read request, accessinga first FTL table entry corresponding to the first read request, and obtaining a first physical address recorded by the first FTL table entry; if the physical block or the block strip containing thefirst physical address is in the erased state, replaying the first read request; wherein even if the first FTL table entry is locked, the first physical address recorded by the first FTL table entry is obtained.
