Memory device with a dynamic fuse array

Abstract:

Methods, systems, and devices for memory device with a dynamic fuse array are described. Techniques and apparatus are described herein for storing an address of a set of the array of latches that is associated with a set of the array of fuses. A se of an array of fuses may include a first portion for indicating the value of the parameter and a second portion for indicating an address of a set of the array of latches that is to receive the parameter stored in the first portion. An enabled set of fuses may indicate that the block is storing a value of a parameter for operating the memory device. By storing the address for the set of the array latches in the set of the array of fuses, a memory device may have a dynamic mapping between the array of latches and the array of fuses. Such a dynamic mapping may reduce an area used by the array of fuses and may make some parameters modifiable.
