Abstract
Digit equilibrate current is reduced during self-refresh mode by reducing the time that the sub-arrays in a volatile memory are precharged with the bleeder device enabled. A selected sub-array is precharged with the bleeder device enabled one cycle prior to having a given row of memory cells refreshed. An auto-refresh counter and row address block are used to generate a section address and a row address of memory cells to refresh. Each sub-array has a given row of memory cells refreshed before another row of memory cells in a given sub-array is refreshed.
