Abstract
Key value (KV) pair data includes a key and a value, where the key addresses the value. The value may include one or more flash management units (FMUs). Because the value is read in order, sequentially from one FMU to a next FMU, end-to-end (E2E) protection of the value may be optimized and improved. E2E protection may including using checksum signatures, of which cyclic redundancy code (CRC) signatures are but one example, to ensure that corrupted data is not returned to a host device. Optimizing checksum signatures used to protect the value may include generating an aggregated checksum signature for each FMU based on a current FMU and each previous FMU of the value or only generating a single checksum signature for an entirety of the value. Thus, characteristics of the value may be taken advantage of in order to improve and optimize E2E protection.
