Abstract
Some examples described herein provide for an encrypted data quantization apparatus and method, for example a memory controller to quantize encrypted data using a cache. One or more embodiments includes obtaining a first set of plaintext data bits to be stored in a memory device using an encryption scheme. A memory address for encrypted data bits to be stored in the memory device is identified for a first subset of plaintext data bits. A second set of plaintext data bits associated with the memory address is obtained from a cache, if present. The second set of plaintext data bits are modified according to the first set of plaintext data bits to be stored in the memory device to generate a third set of plaintext data bits that are then encoded according to the encryption scheme for storage in the memory device.
