Abstract

A computer-implemented method, according to one embodiment, includes: receiving a data access command which corresponds to data stored on NVRAM at a logical block address, and using content-addressable memory (CAM) to determine whether the logical block address corresponds to an active read modify write operation. In response to determining that the logical block address corresponds to an active read modify write operation, the data access command is satisfied using a first procedure. However, in response to determining that the logical block address does not correspond to an active read modify write operation, the data access command is satisfied using a second procedure. Moreover, using the CAM to determine whether the logical block address corresponds to an active read modify write operation is completed in a single clock cycle of the CAM.
