Abstract
A memory device, system, and/or method are provided for performing a page state informing function. The memory device may compare one or more row addresses received along with a command, determine the page open/close state according to a page hit or miss generated as a result of comparison, count read or write commands with respect to pages corresponding to a same row address, and determine the page open/close state according to a read or write command number generated as a result of counting. The memory device may determine a page open/close state with respect to a corresponding page based on a page hit/miss and a read or write command number and output a flag signal. The memory device may provide the page open/close state for each channel. A memory controller may establish different page open/close policies for each channel.
