Total Claims: 14
Claim 1
Independent Claim
157 words
An assemblage element of circuits for connecting together a fixed resistor memory and its associated circuits comprising: a principal rectangular board, provided with an edge which has contact pads on its two faces by which the board is pluggable into a corresponding first connector, said board carrying at least one second connector on each of its two faces spaced apart from said edge, each second connector receiving a pluggable cardplane disposed parallel to and spaced apart from said principal board, each of said card-planes being composed of a rectangular board, which carries on each of its two faces, in addition to printed circuits, a resistor memory plane and a switching matrix for the selection of the word lines of the memory, said principal board carrying in addition, on each of its two faces, between said second connector and said contact pads, a plurality of read amplifiers coupled to the memory planes and a plurality of coupling circuits.
Claim 2
Dependent Claim
157 words
An assemblage element of circuits for connecting together a fixed resistor memory and its associated circuits comprising: a principal rectangular board, provided with an edge which has contact pads on its two faces by which the board is pluggable into a corresponding first connector, said board carrying at least one second connector on each of its two faces spaced apart from said edge, each second connector receiving a pluggable cardplane disposed parallel to and spaced apart from said principal board, each of said card-planes being composed of a rectangular board, which carries on each of its two faces, in addition to printed circuits, a resistor memory plane and a switching matrix for the selection of the word lines of the memory, said principal board carrying in addition, on each of its two faces, between said second connector and said contact pads, a plurality of read amplifiers coupled to the memory planes and a plurality of coupling circuits.
Claim 3
Dependent Claim
44 words
