摘要:
A memory device comprises a memory array, at least one row address buffer, a set of row data buffers, a row decoder, an array of sense amplifiers, and a demultiplexer. The memory array comprises data elements organized into rows and columns. Each of the rows is addressable by a row address. Each of the data elements in each of the rows is addressable by a column address. The at least one row address buffer holds a selected row address of a set of successive selected row addresses. The set of row data buffers holds respective contents of selected rows that correspond to the set of successive selected row addresses. The row decoder decodes the selected row address to access a selected row. The array of sense amplifier reads the selected row and transmits content of the selected row to one of the row data buffers through the demultiplexer, and writes the content of the selected row back to the selected row.

An on-chip sensor measures dynamic power supply noise, such as voltage droop, on a semiconductor chip. In-situ logic is employed, which is sensitive to noise present on the power supply of functional logic of the chip. Exemplary functional logic includes a microprocessor, adder, and/or other functional logic of the chip. The in-situ logic performs some operation, and the amount of time required for performing that operation (i.e., the operational delay) is sensitive to noise present on the power supply. Thus, by evaluating the operational delay of the in-situ logic, the amount of noise present on the power supply can be measured.

An apparatus including a ring oscillator (400) and related methods are disclosed. The ring oscillator (400) includes at least two ring loops. A first ring loop (420) includes a plurality of series coupled delay cells. At least one additional ring loop (430) includes a plurality of series coupled delay cells. The at least one additional ring loop (430) is coupled to the first ring loop (420) by one or more common delay cells (410) shared between the first ring loop (420) and the at least one additional ring loops.

摘要:
In certain aspects, a method for temperature monitoring comprises receiving temperature readings from a plurality of temperature sensors on a chip, and determining an average or a sum of the temperature readings from the temperature sensors. The sum may be a weighted sum of the temperature readings. The method also comprises computing a temperature at a location on the chip based on the average or sum of the temperature readings. The location may be located at approximately a centroid of the locations of the temperature sensors, an estimated hotspot location on the chip, or another location on the chip.
摘要:
A computing system includes at least one functional unit and a magnetic random access memory (MRAM) block coupled to the at least one functional unit. The MRAM block is configured to store a functional state of the at least one functional unit during a power down state of the at least one functional unit.
