A method of making a resilient tampon includes the steps of providing binder fibers having an average fiber length of at least 35 mm; combining the binder fibers to form a loose fleece; activating the binder fibers; and compressing a portion of the loose fleece into a pledget after activating the binder fibers. In an embodiment, a memory controller stores memory sparing information which is specific to a first line of memory in a memory coupled to and controller by the memory controller. The edge selector generates in response to a timing edge, as an output waveform, the waveform corresponding to a first data which is one of the two divided data of the total bit number. The power supply circuitry may bias the power amplifier circuitry with a power supply voltage.
