Devices with adjustable dual-polarity trigger- and holding-voltage/current for high level of electrostatic discharge protection in sub-micron mixed signal CMOS/BiCMOS integrated circuits

Symmetrical/asymmetrical bidirectional S-shaped I-V characteristics with trigger voltages ranging from 10 V to over 40 V and relatively high holding current are obtained for advanced sub-micron silicided CMOS (Complementary Metal Oxide Semiconductor)/BiCMOS (Bipolar CMOS) technologies by custom implementation of P1-N2-P2-N1//N1-P3-N3-P1 lateral structures with embedded ballast resistance 58, 58A, 56, 56A and periphery guard-ring isolation 88-86. The bidirectional protection devices render a high level of electrostatic discharge (ESD) immunity for advanced CMOS/BiCMOS processes with no latchup problems. Novel design-adapted multifinger 354/interdigitated 336 layout schemes of the ESD protection cells allow for scaling-up the ESD performance of the protection structure and custom integration, while the I-V characteristics 480 are adjustable to the operating conditions of the integrated circuit (IC). The ESD protection cells are tested using the TLP (Transmission Line Pulse) technique, and ESD standards including HBM (Human Body Model), MM (Machine Model), and IEC (International Electrotechnical Commission) IEC 1000-4-2 standard for ESD immunity. ESD protection performance is demonstrated also at high temperature (140° C.). The unique high ratio of dual-polarity ESD protection level per unit area, allows for integration of fast-response and compact protection cells optimized for the current tendency of the semiconductor industry toward low cost and high density-oriented IC design. Symmetric/asymmetric dual polarity ESD protection performance is demonstrated for over 15 kV HBM, 2 kV MM, and 16.5 kV IEC for sub-micron technology.

Method and structure for automated switching between multiple contexts in a storage subsystem target device

In a storage target device controller capable of managing multiple command contexts, methods and associated apparatus are provided for automatically managing the plurality of contexts using a state machine model. The state machine model is operable on a target device controller having an active context register set for processing of the presently active transfer on the host channel and an inactive context register set for storing an inactive context. The active context register set and inactive context register set are rapidly and automatically swapped by operation of the state machine model to resume or start processing of an inactive context. Additional inactive contexts are stored in a buffer memory associated with the target device controller. The inactive context register set is automatically stored into a selected one of the additional inactive contexts or loaded from a selected one of the additional inactive contexts by operation of the state machine model of the present invention. The state machine model performs appropriate swap, load, and store operations for contexts in accordance with priorities to improve performance of the target device. The highest priority is an auto-write context corresponding to a write command for which data will be imminently received on the host channel. The next priority is the disk context so as to provide sufficient host channel activity to maintain continuous disk channel operation. The last priority is any other context corresponding to any other command which is neither an auto-write context or the present disk context.
