ACCESSING MEMORY DEVICES VIA SWITCHABLE CHANNELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17898160 titled 'ACCESSING MEMORY DEVICES VIA SWITCHABLE CHANNELS
Simplified Explanation
The memory sub-system described in the patent application includes a memory sub-system controller with multiple controller channels, memory devices with multiple memory dies, and a channel switch circuit connecting the controller channels to the memory channels of the memory devices.
- The memory sub-system controller manages data flow between the controller channels and memory channels.
- Each memory channel corresponds to a specific memory die within a memory device.
- The channel switch circuit receives channel mappings from the controller, which specify the relationship between controller channels and memory channels.
- Data from each controller channel is routed to the corresponding memory channel based on the channel mappings.

Original Abstract Submitted
A memory sub-system includes a memory sub-system controller comprising a plurality of controller channels, one or more memory devices, each of which comprises a respective plurality of memory dies, and a channel switch circuit coupled between the plurality of the controller channels and a plurality of memory channels of the one or more memory devices, where each memory channel corresponds to a respective one of the plurality of memory dies of one of the memory devices, the channel switch circuit comprising command processing logic configured to: receive, from the memory sub-system controller, a plurality of channel mappings, each of which identifies a particular one of the controller channels and a particular one of the memory channels, and route data from each controller channel to a respective one of the memory channels that is associated with the controller channel by a respective one of the channel mappings.
