Abstract
Several embodiments of systems incorporating nonvolatile memory devices are disclosed herein. In one embodiment, a system can include a central processor (CPU) and a nonvolatile memory device operably coupled to the CPU. The nonvolatile memory device can include a memory that stores pre-measurement instructions that are executable by the nonvolatile memory upon startup, but not executable by the CPU upon startup. In operation, the pre-measurement instructions direct the nonvolatile memory to take a measurement of at least a portion of its contents and to cryptographically sign the measurement to indicate that the measurement was taken by the nonvolatile memory device. In one embodiment, the CPU can use the measurement to determine whether the nonvolatile memory device is trustworthy.
