Title: Innovations of Jonathan E Lachman
Introduction
Jonathan E Lachman is a notable inventor based in Fort Collins, CO (US). He holds a total of 12 patents that showcase his contributions to the field of technology and engineering. His work primarily focuses on improving the efficiency and functionality of microprocessors and memory cells.
Latest Patents
One of his latest patents is titled "Method and apparatus for achieving higher product yields by using fractional portions of imbedded memory arrays." This invention provides a circuit and method for obtaining a fully functional microprocessor using only a fraction of the available on-chip cache. The memory sub-arrays of the on-chip cache are tested to determine which sub-arrays are functional. After determining which sub-arrays are functional, a set of sub-arrays is selected that constitute a binary fraction of the cache. The CPU is initialized to accommodate a smaller address space corresponding to the size of the selected sub-arrays. Finally, a group of signals are programmed to allow the CPU access to the selected sub-arrays.
Another significant patent is the "System and method for reducing leakage in memory cells using wordline control." An embodiment of this invention provides a circuit for reducing power in memory cells. The input of the circuit is connected to the wordline of the memory cells. When the wordline is active, the output of the circuit applies a voltage near VDD to the positive voltage supply node of the memory cells. When the wordline is inactive, the output of the circuit applies a voltage that is reduced by at least one V from VDD to the positive voltage supply node of the memory cells.
