Abstract
Memory devices, controllers and associated methods are disclosed. In one embodiment, a memory device is disclosed. The memory device includes storage cells that are each formed with a metal-oxide-semiconductor (MOS) transistor having a floating body. Data is stored as charge in the floating body. A transfer interface receives a read command to access data stored in a first group of the storage cells. Sensing circuitry detects the data stored in the first group of storage cells. The transfer interface selectively performs a writeback operation of the sensed data associated with the read command.
