Abstract: Providing efficient handling of memory array failures in processor-based systems is disclosed. In this regard, in one aspect, a memory controller of a processor-based device is configured to detect a defect within a memory element of a plurality of memory elements of a memory array. In response, a disable register of one or more disable registers is set to correspond to the memory element to indicate that the memory element is disabled. The memory controller receives a memory access request to a memory address corresponding to the memory element, and determines, based on one or more disable registers, whether the memory element is disabled. If so, the memory controller disallows the memory access request. Some aspects may provide that the memory controller, in response to detecting the defect, provides a failure indication to an executing process, and subsequently receives, from the executing process, a request to set the disable register.

Abstract: The search key and key fields of a CAM in a cache are encoded with a Hamming distance of at least two to increase the speed of the CAM by ensuring each mismatching match line is discharged by at least two transistors in parallel. Where the cache is physically tagged, the search key is a physical address. The page address portion of the physical address is encoded prior to being stored in a TLB. The page offset bits are encoded in parallel with the TLB access, and concatenated with the encoded TLB entry. If a page address addresses a large memory page size, a plurality of corresponding sub-page addresses may be generated, each addressing a smaller page size. These sub-page addresses may be encoded and stored in a micro TLB. The encoded key and key field are tolerant of single-bit soft errors.

Abstract: A CAM bank is functionally divided into two or more sub-banks, without replication CAM driver circuits, by disabling all match line discharge circuits in the bank, and selectively enabling the discharge circuits in comprising sub-banks. At least one selectively actuated switching circuit is interposed between the virtual ground node of each discharging comparator in the discharge circuit of a sub-bank and circuit ground. When the switching circuit is in a non-conductive state, the virtual ground node is maintained at a voltage level sufficiently above circuit ground to preclude discharging a connected match line within the CAM access time. When the switching circuit is placed in a conductive state, the virtual ground node is pulled to circuit ground and the connected match line may be discharged by a miscompare. Control signals, which may be decode from address bits, are distributed to the switching circuits to defined the CAM sub-banks.

The apparatus sometimes may be referred to as local match line hold latch, and is a device that stores the value of a local match line comparison result the first time that a search operation occurs, and will stay at that value until the value of the compare data in of the local match line changes.
