Publication number: 20240111673Abstract: Apparatus and methods are disclosed, including memory devices and systems. Example memory devices, systems and methods include a buffer interface to translate high speed data interactions on a host interface side into slower, wider data interactions on a DRAM interface side. The slower, and wider DRAM interface may be configured to substantially match the capacity of the narrower, higher speed host interface. In some examples, the buffer interface may be configured to provide multiple sub-channel interfaces each coupled to one or more regions within the memory structure and configured to facilitate data recovery in the event of a failure of some portion of the memory structure. Selected example memory devices, systems and methods include an individual DRAM die, or one or more stacks of DRAM dies coupled to a buffer die.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Brent Keeth, Owen Fay, Chan H. Yoo, Roy E. Greeff, Matthew B. Leslie
