Abstract: Examples include techniques for determining validity of a memory used with a memory controller. Examples include a system having a memory device including a non-volatile memory and a memory controller, where the memory controller includes a validation component including a hash function and a hash table. In embodiments, the validation component performs, during a time of manufacturing of the memory controller, a test of the non-volatile memory to produce first test results, generates a first hash of the first test results using the hash function, and stores the first hash in the hash table. Later, the validation component performs, during a time of use of the memory controller after the time of manufacturing, the test of the non-volatile memory to produce second test results, generates a second hash of the second test results using the hash function, compares the first hash from the hash table with the second hash, and indicates an invalid memory when the first hash does not match the second hash.
