Abstract: A processing device in a memory sub-system identifies an indication of a completion of a memory access command directed to a memory device and determines whether there are other memory access commands directed to the memory device that are pending. Responsive to determining that there are other memory access commands pending, the processing device coalesces additional indications of completions of the other memory access commands that are available within a threshold period of time with the indication of the completion into a completion data chunk and sends the completion data chunk to a host system. The host system is to store the completion data chunk as one or more completion queue entries in a completion queue in a host memory of the host system via a single host memory write operation.

Abstract: Various embodiments include methods implemented in a processor for management of cryptographic keys of an integrated cryptographic engine. Embodiments may include detecting a cryptographic key access control event, determining whether the cryptographic key access control event is for disabling cryptographic key access at a cryptographic key memory of the integrated cryptographic engine, disabling cryptographic key access at the cryptographic key memory in response to determining that the cryptographic key access control event is for disabling cryptographic key access at the cryptographic key memory, and maintaining one or more cryptographic keys at the cryptographic key memory for which cryptographic key access is disabled. Embodiments may further include enabling cryptographic key access at the cryptographic key memory in response to determining that the cryptographic key access control event is not for disabling cryptographic key access at the cryptographic key memory.
