Latest Patents

One of Schumacher's latest patents is titled "Method and apparatus for data capture on a bi-directional bus." This invention provides a method for reading data from a memory module over a bi-directional bus. The process begins with issuing a read command, followed by transitioning a strobe signal from a mid-rail state to a logical low state. A read enable signal is then transitioned prior to the first falling edge of the strobe signal, which indicates the earliest availability of valid read data. The valid read data is subsequently read in response to the read enable signal transition. This patent also includes a microprocessor and a system for reading data over a bi-directional bus.

Another significant patent by Schumacher is "Logic edge timing generation." This invention involves an edge generation circuit that phase delays pulses of a first signal propagated on an integrated circuit. The circuit consists of a first variable delay circuit, a delay line located off the integrated circuit, and a second variable delay circuit. The first variable delay circuit produces a second signal that is in phase with the first signal. The delay line then generates a third signal, which is delayed in phase from the second by a precise amount. Finally, the second variable delay circuit produces a fourth signal that is in phase with the third signal.
