ABSTRACT:
A memory system provides includes multiple memory devices or banks of memory devices that are assigned frequency pass-bands. Each memory device includes frequency translation circuitry to up-convert and down-convert data signals to and from the assigned frequency pass-band. Some embodiments include simultaneous bidirectional communications between memory devices and a controller by assigning multiple frequency pass-bands to each memory device or bank of memory devices. A memory system substrate is provided with bandpass filters between memory device footprints and other device footprints.
