Abstract
A method of performing a self refresh of memory cells in a memory device. The memory device includes a first group of cell blocks and a second group of cell blocks and each cell block of the first group shares at least one sense amplifier with a cell block of the second group. The method includes simultaneously activating each cell block of the first group. While the cell blocks of the first group are activated, each memory cell in the first group is refreshed. The method further includes simultaneously activating each cell block of the second group. While the cell blocks of the second group are activated each memory cell in the second group is refreshed.
