Abstract
In an embodiment of the invention, a method is provided for isolating a ferroelectric memory from a power supply during a write-back cycle or a write cycle of the ferroelectric memory. After it is determined that a write-back cycle or a write cycle will occur in the ferroelectric memory, the power supply is electrically disconnected from the ferroelectric memory before a write-back cycle or a write cycle occurs. Energy during the write-back cycle or the write cycle is provided to the ferroelectric memory by one or more capacitors in this embodiment. After the write-back cycle or the write cycle has ended, the power supply is electrically connected to the ferroelectric memory and the capacitors.
