Latest Patents

Michael J Sheehan holds 1 patent for his invention related to read only memory. His patent describes an FET read only memory array that features bit locations arranged in rows and columns. This design utilizes a dynamic array and static sensing to improve memory access and reliability. The invention allows for a dynamic first address to select the gate line of a chosen column, while a second address selects the source line or lines to access one or more bits within that column. The presence or absence of a gate at a selected bit location determines the logic level present at the sense or drain line serving that bit location. Additionally, the design includes a column of FET bit positions, each equipped with a gate, which is activated towards the end of the cycle to eliminate any charge on a sense line in preparation for the next cycle. The sensed output from a selected bit location is latched until a reset occurs.
