Abstract
A base neural semiconductor chip (10) including a neural network or unit (11(#)). The neural network (11(#)) has a plurality of neuron circuits fed by different buses transporting data such as the input vector data, set-up parameters, and control signals. Each neuron circuit (11) includes logic for generating local result signals of the 'fire' type (F) and a local output signal (NOUT) of the distance or category type on respective buses (NR-BUS, NOUT-BUS). An OR circuit (12) performs an OR function for all corresponding local result and output signals to generate respective first global result (R*) and output (OUT*) signals on respective buses (R*-BUS, OUT*-BUS) that are merged in an on-chip common communication bus (COM*-BUS) shared by all neuron circuits of the chip. In a multi-chip network, an additional OR function is performed between all corresponding first global result and output signals (which are intermediate signals) to generate second global result (R**) and output (OUT**) signals, preferably by dotting onto an off-chip common communication bus (COM**-BUS) in the chip's driver block (19). This latter bus is shared by all the base neural network chips that are connected to it in order to incorporate a neural network of the desired size. In the chip, a multiplexer (21) may select either the intermediate output or the global output signal to be fed back to all neuron circuits of the neural network, depending on whether the chip is used in a single or multi-chip environment via a feed-back bus (OR-BUS). The feedback signal is the result of a collective processing of all the local output signals.

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.
