destructive read

noun[before a noun]1

1. •
   A read operation that inherently erases the data that was read, requiring it to be immediately written back to the storage medium to prevent loss of data.

   • Although ferroelectric RAM has many advantages over conventional DRAM, it does share one of DRAM's disadvantages: as with DRAM, reading a FeRAM cell is a destructive read process which erases any data in the cell. When using FeRAM for persistent nonvolatile storage, this destructive-read nature can potentially result in data loss or corruption if power to the device is suddenly lost during a read operation.
