摘要： A memory device that accurately tracks memory operations includes a vertical loopback for tracking a sense clock signal to a row address decoder, and read and write reference bit lines in a reference column that include loopbacks for vertically tracking a selected bit line during read and write operations. Preferably the widths of word lines and a sense line are equal to enable the sense line to horizontally track any selected word line. The memory device also includes tri-state input/output (I/O) latches to latch sense amplifier outputs. A drive circuit of the tri-state I/O latch is disabled when the output is available at the corresponding sense amplifier and enabled when the output is latched by the latch circuit.

摘要： A system for detecting soft errors in a memory device includes a latch, a master flip-flop and a slave flip-flop. The latch receives input data (control and/or address signals) at the beginning of a memory operation in response to a rising edge of a first clock signal. The output of the latch is provided to the master flip-flop. The master flip-flop continuously receives and stores the latch output during the memory operation based on a second clock signal. The slave flip-flop receives and stores the output of the master flip-flop at the end of the memory operation based on the second clock signal. A comparator compares the input data with the output of the slave flip-flop to detect soft errors that occur during the memory operation.

摘要： A weight management mat for passively and automatically monitoring weight for one or more individuals in a household. The weight management mat generally includes a housing having an upper mat and a lower mat between which is sealed a pair of perpendicular sensor arrays. Each sensor array includes fiber optic cables laid out in a grid pattern. One or more microbend inducers act to induce detectable microbends in the fiber optic cables when an individual steps on the upper mat. The change in light intensity caused by these microbends is recorded by photodetectors and processed by a microcontroller. The present invention may be utilized to identify each unique individual stepping on the present invention by the pressure map of their feet. Thus, recorded weight measurements may be tracked to aid in weight management.
