Abstract
Embodiments of the disclosure are drawn to apparatuses and methods for timing refresh operations in a memory device. An apparatus may include an oscillator that provides a periodic signal to one or more refresh timer circuits. Each of the refresh timer circuits is associated with a respective memory bank in the memory device. The refresh timer may include a counter block and a control logic block. The control logic block may gate the periodic signal to the counter block. The counter block may count the row active signal time and the row precharge time. The counter signals may be used by the control logic block to output a number of pumps of a refresh operation.
