Introduction
Gurupada Mandal is a notable inventor based in Santa Clara, CA (US). He has made significant contributions to the field of integrated circuits, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of electronic components.
Latest Patents
Mandal's latest patents include a "Fuse sensing scheme with auto current reduction" and a "Bitline booster circuit and method." The fuse sensing scheme introduces an improved circuit for sensing and programming fuses in integrated circuits. This circuit comprises a fuse cell, a reference circuit, a sense amplifier, and a level detector. It implements a two-stage sensing scheme that utilizes current-mode sensing and an auto-read current reduction scheme. The circuit automatically raises the virtual ground if the high-voltage power supply exceeds the core supply by a fixed DC voltage, thereby preserving the integrity of unblown fuses. The invention features four modes of operation: 'Normal Read,' 'Unblown_Read,' 'Blown_Read_1,' and 'Blown_Read_2,' with the default mode being 'Normal Read.'
The bitline booster circuit enhances bitline performance, allowing long bitlines with numerous memory cells to discharge to a digital zero more quickly. This circuit requires only two additional NOR gates, two transistors, and one control signal, making it efficient in terms of component usage and silicon area.
