Claim 0:
1. A method to secure a region in a storage entity and to authenticate a thread to permit or block access to the region comprising:
storing a group key value into a group key field of a key register of the region; and
storing a process key value into a process key field of the key register;
matching a group key of a process group with the group key value in the group key field of the key register to authenticate and affirm or deny permission to access the region, wherein the process group is identified using a process group identifier; and
matching a process key of a process with the process key value in the process key field of the key register to authenticate and affirm or deny permission to access the region, wherein the process is identified by a process identifier; and
responsive to the process key match and group key match, affirming access permission, and responsive to affirming access permission, entering the region into a power state of operation, and wherein the storage entity is configured to hold at least one array that is accessible by rows and columns, and wherein, the at least one array is also accessible by both rows and columns concurrently.
