Bit inversion techniques for memory system repair indications

Abstract

Methods, systems, and devices for bit inversion techniques for memory system repair indications are described. A memory system may store an address of a failed access line or an inversion of the address based on a quantity of bits having a first bit value. For example, if an address has a quantity of ''s that is greater than a threshold, the memory system may store an inversion of the address by inverting the address and setting one-time programmable (OTP) elements to indicate the inverted ‘’s. The memory system may also store an additional inversion bit to indicate the inversion of the address. For reading the OTP elements, the memory system may interpret an address as inverted or non-inverted based on the inversion bit. The memory system may also indicate one or more steps of a repair process to a host system to facilitate communication during repair procedures.
