Abstract: A method performed by a storage device for reducing latency of read operations performed on the storage device, includes: transmitting Host Memory Buffer (HMB) destination information to a host device. The HMB destination information relates to a read destination space reserved within a HMB of the host device. The method also includes receiving a read request from the host device for performing at least one data read operation on a memory of the storage device. The read request specifies data to be read from the memory of the storage device. The method further includes: performing the at least one data read operation on the memory for reading the data specified in the read request and transmitting the data read from the memory to the read destination space reserved within the HMB of the host device.

Abstract: A method of accessing data from a data storage device includes transmitting a request including a first part to the data storage device, based on availability of memory in host device. The first part includes data access information and one or more parameters for accessing data from data storage device. The method further includes receiving a first notification from the data storage device, indicating a transfer of the data to a storage buffer associated with the data storage device. The method further includes accessing the data from the data storage device by transmitting second part of request to the data storage device. The second part includes buffer information associated with a host buffer of host device. The data is transferred by the data storage device from the storage buffer to the host buffer of host device using buffer information.
