Abstract
An apparatus and method are provided for using a page buffer of a memory device as a temporary cache for data. A memory controller writes data to the page buffer and later reads out the data without programming the data into the memory cells of the memory device. This allows the memory controller to use the page buffer as temporary cache so that the data does not have to occupy space within the memory controller's local data storage elements. Therefore, the memory controller can use the space in its own storage elements for other operations.
