ABSTRACT:
A system and method in a radio frequency identification (RFID) tag for writing and erasing user memory. A write command is received at the tag to write data into user memory of the tag. Based on receipt of the write command, a user memory flag in a first memory bank of the tag is set, and the data is written into a second memory bank of the tag. An erase command is received at the tag to erase data stored in the user memory of the tag. Based on receipt of the command to erase, the user memory flag in the first memory bank is cleared, and data stored in the second memory bank is erased.
