Technology is disclosed for dynamically assigning apps to non-volatile memory based on monitoring the apps' usage of memory resources. For a memory system having a high endurance section, such as binary (or single level cell, SLC) memory, and a lower endurance section, such as multi-level cell (MLC) memory, an app, including both the code for executing the app and the associated data payload, may initially be stored in the lower endurance section. The memory system monitors the activity of the app for high levels of activity and, if the app is being frequently written, the memory system notifies the host. In response, the host can request the memory system to move the app or just its associated payload to the high endurance section.

Non-volatile storage system with dynamic allocation of applications to memory based on usage monitoring

Technology that provides security for a requestor of data stored in a non-volatile memory device is disclosed. In one aspect, the non-volatile memory device provides data on a host interface only if a digest for the data matches an expected digest for the data. The non-volatile memory device may store expected digests for data for various logical addresses. Upon receiving a request on the host interface to read data for a logical address, the non-volatile memory device may access the data for the logical address, compute a digest for the accessed data, and compare the computed digest with the expected digest. The non-volatile memory device provides the accessed data on the host interface only if the computed digest matches the expected digest, in one aspect. The non-volatile memory device may be used to provide a secure boot of a host.

Non-volatile memory device with secure read

A non-volatile memory device uses physical authentication to enable the secure programming of a boot partition, when the boot partition is write protected. This physical authentication can also be used to enable other features/functions.
