摘要： Providing for a serial array memory transistor architecture that achieves high read speeds compared with conventional serial array memory is described herein. By way of example, the serial array memory can be connected to and can drive a gate voltage of a small capacitance pass transistor, to facilitate sensing memory transistors of the serial array. The pass transistor modulates current flow or voltage at an adjacent metal bitline, which can be utilized to sense a program or erase state(s) of the memory transistors. Due to the small capacitance of the pass transistor, read latency for the serial array can be significantly lower than conventional serial array memory (e.g., NAND memory). Further, various mechanisms for forming an amplifier region of the serial array memory comprising discrete pass transistor are described to facilitate efficient fabrication of the serial array memory transistor architecture.

摘要： Memory devices having improved BVdss characteristics and methods of making the memory devices are provided. The memory devices contain bitline dielectrics on bitlines of a semiconductor substrate; first spacers adjacent the side surfaces of the bitline dielectrics and on the upper surface of the semiconductor substrate; a trench in the semiconductor substrate between the first spacers; and second spacers adjacent the side surfaces of the trench. By containing the trench and the first and second spacers between the bitlines, the memory device can improve the electrical isolation between the bitlines, thereby preventing and/or mitigating bitline-to-bitline current leakage and increasing BVdss.
