An RFID tag includes multiple memory blocks that can be independently powered. Blocks can be selected automatically, simultaneously, and/or in sequence based on a memory access request received by the RFID tag. A memory block can be selected for powering based on address data included in or derived from a memory access request. Power to a memory block can be controlled by memory block selector which activates one or more power control transistors associated with memory blocks based on the memory access request. A compatible tag reader can be configured to instruct a tag to power/unpower individual memory blocks.
