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.

Abstract: The invention relates to a method for reducing the number of flip-flops in a VLSI design that require data retention, thereby eliminating the respective backup cells for those flip flops, the method comprises the steps of: (a) defining one or more criteria for non-essentiality of backup cells! (b) during the physical design stage, analyzing the VLSI design based on said one or more criteria for non-essentiality, and finding those flip-flops that meet these criteria, wherein said analysis is performed at the gate level, independent from any higher level representation of the design; and (c) eliminating from the VLSI design those backup cells for all non-essential flip-flops that meet one or more of said criteria for non-essentiality, thereby leaving in the design only those backup cells for those flip-flops that do not meet any of said criteria.
