摘要： A method and circuit write a memory cell. The method applies a pulse train to a write line connected to the memory cell. The number of pulses in the pulse train is not predetermined. The method compares a value on the input side of the cell to a reference value, wherein the input side of the memory cell provides an indication that a writing operation is complete. The method discontinues the pulse train on the write line, in response to the comparing step, preferably if the value on the write line exceeds the reference value. Preferably, the pulses are short in width and large in magnitude. The method may optionally count the number of pulses in the pulse train, and discontinue the pulse train on the write line and/or declare the cell as unusable if the number of pulses exceeds a predetermined maximum. The circuit comprises a pulse train generator and a comparator. The pulse train generator has an output and an enable input. The output is connected to a write line connected to the memory cell. The output, when enabled, carries a pulse train. The comparator has two inputs and an output. One of the inputs is connected to the write line. The other of the inputs is connected to a reference. The output is connected to the enable input of the pulse train generator, whereby the pulse train generator is disabled or enabled depending upon the comparator output. Optionally, the circuit further comprises a counter that counts pulses and disables the pulse train generator after a predetermined maximum number of pulses. A complete memory system comprises an array of memory cells, a write line, and a pulse train generator and comparator as described above.

摘要： A communication comprises a plurality of digital subscriber line (DSL) links, a first node having at least one application port configured for an elastic service and a plurality of DSL ports, and a second node having at least one application port configured for an elastic service and a plurality of DSL ports. Each of the first and second nodes is configured to interleave data received over the at least one application port across the plurality of DSL ports, each DSL port allocated a set of DSL timeslots for transport of the data received over the at least one application port. When a failure is detected on one of the DSL links, each of the first and second nodes is configured to interleave the data received over the at least one application port across the remaining DSL ports not connected to the failed DSL link without adjusting the set of DSL timeslots allocated to each of the remaining DSL ports for transport of the data from the at least one application port.
