Claim Text:
1. Search circuit for searching a data within a data matrix, comprising: the data matrix arranged in a plurality of data lines, each data line comprising a plurality of data storage nodes, each data storage node being configured so as to store a first state or a second state, the data storage nodes being mainly in the second state, a first test circuit configured for testing the state of one of the data lines, the first test circuit being configured so as to determine whether the tested data line has no data storage node in the first state or whether the tested data line has at least one data storage node in the first state, the first test circuit sending a first code when the tested data line has at least one data storage node in a first state or a second code when the tested data line has no data storage node in the first state, a second test circuit configured for testing the state of the plurality of data storage nodes in the tested data line, the second test circuit being configured so as to send a third code when the tested data storage node is in the first state or a fourth code when the tested data storage node is in the second state, the second test circuit being configured so as to test the data storage nodes of the data line when the first test circuit has sent a first code relative to said tested data line, a receiver configured so as to receive the result from the first test circuit for each tested data line and to receive the results from the second test circuit for the tested storage nodes.
