Abstract
A synaptic array according to the present invention comprises a plurality of electrically-adaptable elements. Electrons may be placed onto and removed from a floating node in each electrically adaptable element associated with at least one MOS insulated gate field effect transistor, usually the gate of the transistor, in an analog manner, by application of first and second electrical control signals generated in response to an adapt signal. The inputs to all synaptic elements in a row are connected to a common row input line. Adapt inputs to all synaptic elements in a column are connected together to a common column adapt line. The current supplied to all amplifiers in a column is commonly provided by a sense line. In order to adapt the synaptic elements in the M row by N column matrix of the present invention, the voltages to which a given column n of the matrix is to be adapted are placed onto the input voltage lines, and the synaptic elements in column n are then simultaneously adapted by assertion of an adapt signal on the adapt line for column n. The vectors of input voltages for adapting successive columns may be placed sequentially onto the row input voltage lines and used to adapt the columns of synaptic elements by assertion of the adapt signals on the appropriate column adapt lines until the entire array is electrically adapted. After each synaptic element has been adapted, the current flowing through it will be maximized when the voltage at the input of the synaptic element equals the voltage to which the synaptic element has been adapted. An electrically adaptable winner-take-all circuit has its inputs connected to the column-sense lines of the array.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
