Abstract: Methods, systems, and devices for initialization techniques for memory devices are described. A memory system may include a memory array on a first die and a controller on a second die, where the second die is coupled with the first die. The controller may perform an initialization procedure based on operating instructions stored within the memory system. For example, the controller may read a first set of operating instructions from read-only memory on the second die. The controller may obtain a second set of operating instructions stored at a memory block of the memory array on the first die, with the memory block indicated by the first set of operating instructions. The controller may complete or at least further the initialization procedure based on the second set of operating instructions.

Abstract: Methods, systems, and devices for authenticated reading of memory system data are described. In some examples, a host system and a memory system may exchange keys used to grant the host system access to one or more protected regions of the memory system. The keys may be symmetric or asymmetric. In some cases, the host system may transmit a read command to access data stored at a protected region of the memory system, along with a signature generated using the key associated with the protected region. The memory system may verify the signature to determine whether the host is authorized to access the protected region, and may transmit the requested data to the host system. In some examples, the memory system may sign the returned data, so that the host system may verify the source of the data.

Abstract: Methods, systems, and devices for authenticated modification of memory system data are described. A host system may transmit a command to program data to a protection region of a memory system, and the host system may sign the command using a key associated with the protection region. In some examples, the host system may transmit the data associated with the command, or the command may include instructions to move the data from another region of the memory system. Upon receiving the command, the memory system may verify the signature to determine whether the host is authorized to modify the protection region, and may program the data as requested by the host system. In some cases, the protection regions of the memory system may be updated, for example by adjusting the size or address range of the protection regions, in response to a command from the host system.

Abstract: Methods, systems, and devices for memory recovery partitions are described. A memory system may include a memory array configured with one or more logical partitions. In some examples, a primary boot image may be stored to a first logical partition and a recovery boot image may be stored to a second logical partition. During a boot operation, the memory system may determine whether the primary boot image includes one or more errors. If the primary boot image includes relatively few (or no) errors, the memory system may boot using the primary boot image. If the primary boot image includes a relatively high quantity of errors (e.g., higher than a threshold quantity of errors), the memory system may autonomously load a recovery boot image stored to the second logical partition.
