Abstract
A storage device and a data access method are provided. The storage device includes a primary storage unit and at least one additional unit. The primary storage unit includes: a primary memory element configured to store secret data and a primary access unit configured to receive an external access command. Each additional unit is configured to receive the external access command. Each additional unit includes: an additional memory element configured to store non-specific data, a local access generation element configured to trigger generating an internal access command based on the external access command, and an additional access unit configured to receive a local access command. The primary storage unit and each additional unit are coupled to a same power rail and a connection wire to simultaneously receive the external access command to parallelly (simultaneously) access the secret data and the non-specific data stored in each additional unit.
