Replacement data buffer pointers
Technology is described herein for operating non-volatile storage. In one aspect, a memory controller replaces an original data buffer pointer(s) to a host memory data buffer(s) with a replacement data buffer pointer(s) to a different data buffer(s) in the host memory. The original data buffer pointer(s) may be associated with a specific read command. For example, the original data buffer pointer(s) may point to data buffer(s) to which data for some range of logical addresses (which may be read from the non-volatile storage) is to be transferred by a memory controller of the non-volatile storage. The replacement data buffer pointer(s) could be associated with a different read command. However, it is not required for the replacement data buffer pointer(s) to be associated with a read command. The replacement data buffer pointer(s) may point to a region of memory that is allocated for exclusive use of the memory controller.
