TECHNOLOGIES FOR MANAGING A RESERVED HIGH-PERFORMANCE MEMORY REGION OF A SOLID STATE DRIVE

摘要

Technologies for establishing and managing a high-performance memory region of a solid state drive include reserving a region of a volatile memory of the solid state drive for storage of host data. Memory accesses received from a host may be directed toward the reserved region of the volatile memory or toward a non-volatile memory of the solid state drive. Due to the structure of the volatile memory, memory accesses to the reserved region may exhibit lower access timing relative to memory accesses to the non-volatile memory. As such, the reserved region may be utilized as storage space for journaling and logging of data and/or other applications. Upon shutdown or a power failure event, data stored in the reserved region of the volatile memory is copied to the non-volatile memory and subsequently reinstated to the volatile memory upon the next initialization event.

主权项

1. A solid state drive for managing a high-performance memory region, the solid state drive comprising:
a non-volatile memory; a volatile memory; and a drive controller to (i) reserve a region of the volatile memory for storage of host data, (ii) receive a storage access request from a host of a computing system, (iii) determine whether the storage access request is directed to the reserved region of the volatile memory, and (iv) access the reserved region of the volatile memory in response to a determination that the storage access request is directed to the reserved region.
