Abstract
A memory device is embedded in (or connected to) a host device. The memory device includes a first boot partition and a second boot partition. The first boot partition stores first boot data. The second boot partition stores second boot data. The memory device includes a pointer that points to either the first boot partition or the second boot partition. The memory device transfers the first boot data from the first boot partition in response to receiving a boot signal from the host and the pointer pointing to the first boot partition. The host attempts to boot using the first boot data. If the host does not boot successfully from the first boot data then the host is booted from second boot data transferred from the memory device without the host requesting that the pointer switch to pointing at the second boot data.
