RESOURCE ACCESS CONTROL

摘要

Various embodiments enable mappings of logical regions to physical regions for a memory resource for data writes to be maintained. A first mapping of logical regions to physical regions and a second mapping of logical regions to physical regions for a memory resource are maintained. The second mapping comprises a safe state of the memory resource. Responsive to receiving a request to write data to a logical region of the logical regions, a first set of data is written to a first physical region of the physical regions according to the first mapping of logical regions to physical regions. Responsive to receiving a request to read data from the logical region of the logical regions, a second set of data is read from a second physical region of the physical regions according to the second mapping of logical regions to physical regions.

主权项

1. A computer system, comprising:
one or more processors; and one or more computer readable storage media having stored thereon computer-executable instructions that are executable by the one or more processors to cause the computer system to enable mappings of logical regions to physical regions for a memory resource for data writes to be maintained, the computer-executable instructions including instructions that are executable to cause the computer system to perform at least the following:
maintain a first mapping of logical regions to physical regions and a second mapping of logical regions to physical regions for a memory resource, the second mapping of logical regions to physical regions comprising a safe state of the memory resource;responsive to receiving a request to write data to a logical region of the logical regions, write a first set of data to a first physical region of the physical regions according to the first mapping of logical regions to physical regions; andresponsive to receiving a request to read data from the logical region of the logical regions, read a second set of data from a second physical region of the physical regions according to the second mapping of logical regions to physical regions.
