receiving write data corresponding to multiple hash values, the write data read from a remote memory, the multiple hash values generated based on the write data, the memory-disaggregated environment including local memory and the remote memory;

selecting a hash value among the multiple hash values for integrity verification based on an access latency of the remote memory to control latency from occurring during the integrity verification; and

verifying integrity of the write data read from the remote memory based on the hash value.
