Abstract
Methods, systems, and devices for repair techniques for coupled host and memory dies are described. For example, to distribute memory access circuitry among multiple semiconductor dies of a stack, a first die may include a set of one or more memory arrays and a first portion of circuitry configured to access the set of memory arrays, and a second die may include a second portion of circuitry configured to access the set of memory arrays. The second portion of the circuitry (e.g., of the second die) may be configured to support various repair techniques for operations with the set of memory arrays, including techniques in response to column failures or serialization failures associated with the first die, or in response to contact or other interconnection failures with or between the first die and the second die, among other techniques that may be differentiated based on an attribution of error conditions.
