Abstract
The present disclosure generally relates to a method and device for accessing more dies per channel in a data storage device. Each flash interface module (FIM) can have any number of bus multiplexers coupled thereto, and each bus multiplexer can have any number of memory devices coupled thereto. The bus multiplexers can be connected in series or in parallel to the FIM. The individual bus multiplexers can be addressed by a chip enable (CE) command that identifies the specific bus multiplexer as well as the specific memory device of the specific bus multiplexer. The information in the CE command allows more dies per channel without creating signal interference (SI) or limiting transmission performance.
