Integrated circuit memory devices including mode registers set using a data input/output bus

Abstract

An integrated circuit memory device may include a memory cell array and a plurality of data input/output pins. The plurality of data input/output pins may be configured to receive data from a memory controller to be written to the memory cell array during a data write operation, and the data input/output pins may be further configured to provide data to the memory controller from the memory cell array during a data read operation. A mode register may be configured to store information defining an operational characteristic of the memory device, and the mode register may be configured to be set using the data input/output bus. Related methods, systems, and additional devices are also discussed.
