摘要： A semiconductor memory device, e.g., a DRAM, which includes a P-type semiconductor substrate, a memory array each memory cell of which includes at least one N-channel MOS transistor, a CMOS peripheral circuit at least partially surrounding the memory array, the peripheral circuit including at least one P-channel MOS transistor formed in an N-type well region formed in the substrate, and at least one N-channel MOS transistor formed in the substrate outside of the N-type well region, and, a P-type minority carrier absorption semiconductor region formed in the substrate between the N-type well region and the memory array. The minority carrier absorption semiconductor region is preferably connected to a source of negative voltage, e.g., the substrate bias voltage, and a separate N-type region formed in the N-type well region is preferably connected to a source of positive voltage, e.g., the power supply voltage, Vdd, of the memory device. The N-type well region functions to absorb or capture hot electrons generated by the N-channel MOS transistor of the CMOS peripheral circuit, and the P-type minority carrier absorption semiconductor region functions to absorb or capture holes which would otherwise combine with the hot electrons to induce substrate current which could deleteriously lower the threshold voltage level of the memory cells of the memory array and thereby degrade the data storage integrity thereof.

摘要： A method, apparatus and system for pre-authenticating ports is disclosed. In one embodiment, an active port facilitating communication of media content between a transmitting device and a receiving device is identified, while the active port are associated with a first High-Definition Content Protection (HDCP) engine. Then, inactive ports that are in idle mode serving as backup ports to the active port are identified, while the inactive ports are associated with a second HDCP engine. Pre-authentication of each of the inactive ports is performed so the pre-authenticated inactive ports can subsequently replace the active port if a port switch is performed.

摘要： A current sense amplifier may include one or more clamping circuits coupled between differential output nodes of the amplifier. The clamping circuits may be enabled during at least a portion of the time that the sense amplifier is sensing the state of a memory cell coupled to a differential input of the sense amplifier. The clamping circuits may be disabled during the time that the sense amplifier is sensing the state of a memory cell at different times in a staggered manner. The clamping circuits may be effecting in making the current sense amplifier less sensitive to noise signals.
