Abstract: A method for rendering data invalid within a memory array is described. The method includes establishing governing metadata for a memory location within a memory array. The method also includes receiving a request to retrieve data from the memory location. The method also includes determining whether color metadata associated with the data matches the governing metadata. The method also includes returning the data when the color metadata matches the governing metadata. The method also includes returning invalidated data when the color metadata does not match the governing metadata.

Abstract: A method for remapping a memory location in a memory array is described. The method includes receiving, by a memory manager, an identification of a first memory location in a memory array that is to be remapped using a remapping procedure performed by a memory manager. The remapping procedure includes selecting a second memory location to store data intended for the first memory location. The procedure also includes writing, in the first memory location, a pointer to the second memory location.

Abstract: According to an example, hierarchal stripe locks may be obtained for a source stripe and a destination stripe. In response to receiving data for the source stripe, the data is written from the source stripe to the destination stripe, and the hierarchal stripe locks are released for the source stripe and the destination stripe. In response to receiving the data-migrated token, the hierarchal stripe locks are released for the source stripe and the destination stripe.

Abstract: Examples disclosed herein provide moving a block of data between a source address and a target address. The examples disclose initiating a data move engine to move the block of data from the source address to the target address. Additionally, the examples disclose moving the block of data from the source address to the target address in a manner which allows a processor to concurrently access the block of data during the move.

Abstract: A method for restricting write access to a non-volatile memory. The method includes receiving a request to write to a protected location in the non-volatile memory and determining whether the protected location is in a write-protected state. If the protected location is not in a write-protected state, the method includes writing data indicated by the request to the protected location. If the protected location is in a write-protected state, the method includes rejecting the request. The protected location stores a validation key to validate the contents of another portion of the non-volatile memory.

Abstract: A method for managing data using a number of non-volatile memory arrays is described. The method includes writing data from a volatile memory region to a first non-volatile memory array. The method also includes writing a remaining portion of the data from the volatile memory region to a second non-volatile memory array in response to detecting that an event has occurred. The second non-volatile memory array has a lower write latency than the first non-volatile memory array.

Abstract: A method for managing a multi-lane serial link is described. The method includes establishing a serial link between a number of integrated circuits across a first number of lanes. The first number of lanes are a subset of a number of available lanes on the serial link. The method also includes selecting to change a transmission state of a second number of lanes. The second number of lanes are a subset of the available lanes. The method also includes changing the transmission state of the second number of lanes while transmitting data on a number of remaining lanes. The method further includes synchronizing the first number of lanes and the second number of lanes.
