Embodiments of the invention provide a column address strobe latency circuit that generates a stable latency signal in a high-speed semiconductor memory device, and a semiconductor memory device including the CAS latency circuit. By this reinforcing portion 112c, it is possible to prevent the core portion 110 from being deformed by water at high pressure. Methods provided include producing a soybean plant by crossing soybean variety XBP55004 with another soybean plant, methods for introgressing a transgenic trait, a mutant trait, andor a native trait into soybean variety XBP55004, methods for producing other soybean varieties or plant parts derived from soybean variety XBP55004, and methods of characterizing soybean variety XBP55004. If an aspect of the domain changes, the domain expert need only modify the knowledge blocks, and the presentations that use the modified knowledge blocks are thereby automatically updated.
