摘要： Systems, methods, circuits, and apparatus including computer-readable mediums for testing bonding pads in multi-die packages, e.g., chiplet systems. An example integrated circuit device includes an integrated circuit, first type bonding pads and second type bonding pads. Each of the first type bonding pads is electrically connected to the integrated circuit and configured to be electrically connected to a corresponding external integrated circuit device. Each of the second type bonding pads is configured to have no electrical connection with the corresponding external integrated circuit device. Each of the first type bonding pads is configured to be electrically connected to a corresponding one of the second type bonding pads. A number of the first type bonding pads can be larger than a number of the second type bonding pads. Each of the second type bonding pads can have a larger pad area for probing than each of the first type bonding pads.

摘要： An integrated circuit includes an array of memory cells that is arranged into rows, main columns, and redundant columns that perform repairs in the array. The main columns and the redundant columns are divided into row blocks. Bit lines couple the main columns to status memory indicating repair statuses of the repairs by the redundant columns. The integrated circuit receives a command, and performs an update on the status memory with the repair statuses specific to particular ones of the row blocks in a portion of the memory accessed by the command. Alternatively or in combination, the status memory has insufficient size to store the repair statuses of multiple ones of the row blocks of the main columns.

摘要： A circuit for voltage detection and protection comprises a first block, a first voltage detector, a second block and a second voltage detector. The first block receives a first voltage supply. The first voltage detector detects the first voltage supply and generates a first detecting signal when detecting the first voltage supply level is out of the first operating voltage range. The second block receives a second voltage supply. The second voltage detector detects the second voltage supply and generates a second detecting signal when detecting the second voltage supply level is out of the second operating voltage range. The first block performs a protection operation on the circuit when monitoring at least one of the first and second detecting signals.

摘要： A method for maintaining a data set includes storing a base copy of the data set in a first non-volatile memory having a first writing speed, storing changes to the data set in a first change data set in a second non-volatile memory having a second writing speed, and generating a current copy of the data set by reading the base copy and the changes. If a threshold number of entries in the first change data set is reached, then part or all of the first change data set is moved into a second change data set in the first non-volatile memory, where the generating step includes reading the second change data set. If a threshold number of entries in the second change data set is reached, then the current copy is generated by reading the base copy and the changes in the first and the second non-volatile memory.
