Arrangement for reducing number of fuses in semiconducting device has decompressor between fuse and fuse latch devices for reading states of fuses of activated master fuse

摘要

The arrangement has a fuse device with fuses associated with master fuses, a fuse latch device with fuse latches associated with master fuse latches and an evaluation stage. There is a dynamic relationship between master fuses and fuses and between master fuse and fuse latches. A decompressor enables the fuses of an activated master fuse to be read out to determine their active or inactive states and form a corresponding data string. The arrangement has a fuse device with master fuses and fuses (F), each master fuse having a given number of associated fuses, a fuse latch device with master fuse and fuse latches (FL) and an evaluation stage (S). There is a dynamic relationship between master fuses and fuses and between master fuse and fuse latches. A decompressor between the fuse device and fuse latch device enables the fuses of an activated master fuse to be read out to determine their active or inactive states and form a corresponding data string. AN Independent claim is also included for the following: a method of reducing number of fuses in semiconducting device.
