Patent attributes
A write request is received to write byte-addressable data corresponding to a first entry of a plurality of entries in a page table, and the byte-addressable data is written in a buffer of a host memory. A read request is received to read byte-addressable data corresponding to a second entry of the plurality of entries in the page table, and a read command is sent to a device using a memory device interface to read the byte-addressable data from a Storage Class Memory (SCM) of the device. According to another aspect, control circuitry of the device uses a block device interface for receiving commands from a host to read and write data in blocks in the SCM. The control circuitry also uses a memory device interface for receiving read commands from the host to read byte-addressable data from the SCM.
