Abstract:

Means were studied for achieving an electrically settable, unpowered memory for integrated circuit counters via a matrix of fusible conductors. The concept stores desired codes by burning out appropriate fuses in a selected row of the fuse matrix. Provision also is made for changing the stored code by burning out appropriate fuses in a new row and recording the location of the operative row via supplementary fusible conductors. To permit fabrication of fuses as part of MOS integrated circuit arrays, compatible fabrication techniques were investigated. Experiments were conducted with four different metals aluminum, nickel, nichrome, and tin. It did not prove possible, however, to make fuses with sufficiently low fusing-power levels to permit burnout control via integrated MOS transistors separate fuse drivers are required. A successful fuze-timer system based on a fusible-conductor memory was developed. Operation of a portion of the system was demonstrated using a breadboard model. Author
