Abstract
A plurality of zone reset counters and a global reset counter are maintained. A zone reset counter represents a number of times a respective zone of a memory device has been reset. The global reset counter represents a measure of central tendency of the plurality of zone reset counters. A write command directed to a target zone of the memory device is received, and responsive to determining that a target portion of the target zone is not open, a value of the zone reset counter of het target zone is compared to the value of the global reset counter. If the value of the target zone reset counter equals or exceeds the value of the global reset counter, a portion from a free block list is allocated to the target zone. The allocated portion has a highest program erase count among the one or more portions in free block list.
