    Abstract: A memory array includes a first subarray of memory cells and a second set of memory cells. The first and second subarrays of memory cells share a set of global word lines. The first and second subarrays of memory cells are coupled to first and second sets of bit lines, respectively. The first subarray includes rows of memory cells coupled to a first set of local word line drivers via a first set of local word lines, respectively. The second subarray includes rows of memory cells coupled to a second set of local word line drivers via a second set of local word lines, respectively. A selected local word line drivers generates a first asserted local word line signal for accessing at least one memory cell for reading or programming purpose in response to receiving a second asserted signal via a global word line and a third asserted signal.

    Abstract: A semiconductor apparatus is provided herein for reducing power when transmitting data between a first device and a second device in the semiconductor apparatus. Additional circuitry is added to the semiconductor apparatus to create a communication system that decreases a number of state changes for each signal line of a data bus between the first device and the second device for all communications. The additional circuitry includes a decoder coupled to receive and convert a value from the first device for transmission over the data bus to an encoder that provides a recovered (i.e., re-encoded) version of the value to the second device. One or more multiplexers may also be included in the additional circuitry to support any number of devices.

    Abstract: A dual-mode PMOS transistor is disclosed that has a first mode of operation in which a switched n-well for the dual-mode PMOS transistor is biased to a high voltage. The dual-mode PMOS transistor has a second mode of operation in which the switched n-well is biased to a low voltage that is lower than the high voltage. The dual-mode PMOS transistor has a size and gate-oxide thickness each having a magnitude that cannot accommodate a permanent tie to the high voltage. An n-well voltage switching circuit biases the switched n-well to prevent voltage damage to the dual-mode PMOS transistor despite its relatively small size and thin gate-oxide thickness.
