Abstract
A memory device includes isolation devices located between-memory cells. A plurality of isolation lines connects the isolation devices to a positive voltage during normal operations but still keeps the isolation devices in the off state to provide isolation between the memory cells. A current control circuit is placed between the isolation lines and a power node for reducing a current flowing between the isolation lines and the power node in case a deflect occurs at any one of isolation devices.
