Abstract: A method of a memory device is provided. The method includes identifying a tag address of a tag memory based, at least partially, on a source index; accessing a cache storage address corresponding to the tag address; comparing tag memory content and at least part of the source index to identify whether a match exists or whether a conflict exists; and in response to identifying whether the match exists or whether the conflict exists, obtaining information from the cache storage address.

Abstract: A method for temperature control. In some embodiments, the method includes sensing a first temperature of an electronic device, determining that the first temperature exceeds a first threshold, and increasing a power supplied to a thermoelectric cooler thermally connected to the electronic device. The increasing of the power may include increasing the power in response to determining that the first temperature exceeds the first threshold.

Abstract: A method of a memory device is provided. The method includes generating, by a controller of the memory device, a hashed index by hashing a source index comprising a namespace identification (NSID) and a keytag with a hash function; accessing, by the controller, a first storage address corresponding to the hashed index; comparing, by the controller, a tag portion corresponding to the first storage address with the source index to identify whether a conflict exists; and in response to identifying whether the conflict exists, obtaining, by the controller, information from the first storage address.

Abstract: Inventive aspects include a device including storage media. The device includes a PMU, and a controller communicatively coupled to the PMU. The PMU determines that an operating power of the device exceeds a threshold, and transmits a signal to the controller to trigger a power reduction operation. The controller throttles one or more operations until the operating power goes below the threshold. Some embodiments include a method for controlling performance of a storage device. The method includes measuring, by a PMU, a power consumption associated with a storage device. The method includes determining, by the PMU, whether the power consumption is greater than a threshold. In response, the method may include setting a performance throttle. The method may include determining, by the PMU, whether the power consumption is less than the threshold. In response, the method may include releasing the performance throttle.

Abstract: A method for managing security keys for an I/O device may include loading a first security key from a primary memory to a security engine, performing a first data transfer operation between a host and the I/O device using the first security key with the security engine, loading a second security key from a secondary memory to the security engine, and performing a second data transfer operation between the host and the I/O device using the second security key with the security engine. The method may further include storing the first security key in the primary memory based on a frequency of use of the first security key. The frequency of use of the first security key may be determined by a pattern of transfers between the host and the I/O device.

Abstract: A method may include transferring data from a host to an encryption offload engine through an interconnect fabric, encrypting the data from the host at the encryption offload engine, and transferring the encrypted data from the encryption offload engine to a storage device through a peer-to-peer connection in the interconnect fabric. The method may further include transferring the encrypted data from the storage device to the encryption offload engine through a peer-to-peer connection in the interconnect fabric, decrypting the encrypted data from the storage device at the encryption offload engine, and transferring the decrypted data to the host through the interconnect fabric. The method may further include transferring the encrypted data from the storage device to the host, and verifying the encryption of the encrypted data at the host.

Abstract: Various aspects include a continuous authentication system for a storage system. The continuous authentication system includes a host having an encryption unit. The continuous authentication system includes a storage device having a decryption unit. The continuous authentication system includes a first physical connection between the host and the storage device. The first physical connection may be configured to transfer I/Os. The continuous authentication system may include a second physical connection between the host and the storage device. The encryption unit may be configured to encrypt a continuous authentication signal. The host may be configured to transmit the continuous authentication signal through the second physical connection. The storage device may be configured to receive the continuous authentication signal through the second physical connection. The decryption unit may be configured to decrypt the continuous authentication signal. When the second physical connection is tampered with, the storage device may stop processing the I/Os.
