Redundancy selection apparatus and method for an array
摘要:
A fused decoder for selecting one or more elements of an array, such as a row of memory, is provided. The corresponding row of memory can be permanently deselected by blowing the fuse of the decoder. Array components such as a redundant row of memory, can be substituted for the deselected component. The decoder includes a gate formed exclusively from NMOS transistors so that the decoder can provide a select signal in response to an address without an PMOS transistor responding to the address- By eliminating PMOS transistors from the gate portion of the decoder, the load presented to the address lines is reduced.
