Abstract
The present disclosure describes analog memories for use in a computer, such as a computer using a combination of analog and digital components/elements used in a cohesive manner.
Claims20
An analog memory, comprising:
- a memory element configured to (i) store an analog signal by storing a first analog signal value representing said analog signal and (ii) output said stored analog signal as an output analog signal, wherein the storing and/or the outputting is performed in response to one or more of a first control signal and a second control signal;
- and
- a reference memory element configured to store a preselected fixed analog signal by storing a second analog signal value representing the preselected fixed analog signal in response to said first control signal.
A method for storing an analog signal, comprising:
- simultaneously and separately storing an analog signal and a reference analog signal;
- and
- determining a validity of said stored analog signal for output based on an amount of decay of a value of said stored reference analog signal relative to an initial value of said reference analog signal.
A memory for storing digital and analog values, comprising:
- a memory management unit,
- an array comprising a first plurality of memory elements for storing an input analog signal by storing an analog value representing the input analog signal, and for outputting said stored input analog signal as an output analog signal, wherein the storing is performed in response to a first command signal from said memory management unit and the outputting is performed in response to a second command signal from said memory management unit,
- a second plurality of reference memory elements configured to store a fixed input analog reference signal by storing an analog value in response to said first command signal from said memory management unit,
- at least one threshold sense block configured to compare said fixed input analog reference signal and said stored input reference analog signals from said reference memory elements, responsive to said second command signal, and providing a first signal when said comparison differs by less than a first amount that indicates the output analog signals from said first plurality of memory elements are suitable for further use,
- a plurality of digital memory elements for storing digital inputs and providing them as output digital values in response to command signals from said memory management unit, and
- a plurality of memory synchronization blocks interconnected with said first plurality of analog memory elements and said plurality of digital memory elements.
3 more elements
An analog memory, comprising:
- at least one memory element configured to (i) store an analog signal by storing a first analog signal value representing said analog signal and (ii) output said stored analog signal as an output analog signal, wherein the storing is performed in response to a first control signal and the outputting is performed in response to a second control signal;
- and
- at least one reference memory element configured to store a preselected fixed analog signal by storing a second analog signal value representing the preselected fixed analog signal in response to said first control signal, and
- one or more sense blocks configured to (i) monitor and detect any change in the second analog signal value stored in said reference memory element and (ii) adjust a changed second analog signal value stored in said reference memory element and a changed first analog signal value stored in said memory element by an amount necessary to compensate for the detected change in response to a third control signal.
