Abstract: A method can include detecting, by a glitch detector coupled via a connection matrix to a first processing unit, an indication of a glitch on a memory system. The method can include notifying, via the connection matrix, at least a second processing unit of the detected indication of the glitch. The method can include subsequent to notifying at least the second processing unit, transmitting via the at least the second processing unit a glitch confirmation signal.

Abstract: Protection for a secure boot procedure can be provided in addition to cryptographic verification of boot firmware associated with the boot procedure. While the boot firmware is being verified, an open sub-system can be placed into a halt state, during which the open sub-system is prevented from performing the boot procedure. The open sub-system can be subsequently placed into a resume state to further perform the boot procedure when the boot firmware is verified. The open sub-system is still prevented from performing the boot procedure even if the boot firmware is verified unless the open sub-system is placed into the resume state again.

Abstract: Protection for a secure boot procedure can be provided in addition to cryptographic verification of boot firmware associated with the boot procedure. While the boot firmware is being verified and executed at a secure sub-system, an open sub-system can be put into a halt state, during which the open sub-system is prevented from performing the boot procedure. The open sub-system is still prevented from performing the boot procedure even if the boot firmware is verified and/or executed unless the open sub-system is put into the resume state again.

Abstract: Systems, apparatuses, and methods related to security management for a ferroelectric memory device are described. An example method can include receiving, at a memory controller and from a host, a command and firmware data. The memory controller can manage a non-volatile memory device, such as a ferroelectric memory device, and the host and the memory controller can communicate using a compute express link (CXL) protocol. The command can be executed to update firmware stored on the non-volatile memory device. The method can further include accessing a first public key from the non-volatile memory device. The method can further include validating the first public key with a second public key within the firmware data. The method can further include validating the firmware data. The method can further include verifying a security version of the firmware data. The method can further include updating the non-volatile memory device with the firmware data.

Abstract: A method can include performing at least one glitch resistance operation and detecting, by a circuit included in a glitch detector coupled via a connection matrix to a first processing unit, an indication of a glitch on a memory system. The method can include notifying, via the connection matrix, at least a second processing unit of the detected indication of the glitch. The method can include subsequent to notifying at least the second processing unit, transmitting via the at least the second processing unit a glitch confirmation signal.

Abstract: Methods, systems, and devices related to field firmware update (FFU). A first memory of a memory module may receive an encrypted segment of a FW package associated with FFU. A decrypted segment of the FW package may be stored by the first memory. A re-encrypted segment of the FW package may be stored by the first memory. The re-encrypted segment of the FW package may be communicated to a second memory of the memory module.
