A cache memory includes: a tag storage section in which one of a plurality of indexes, each index containing a plurality of tag addresses and one suspension-indicating section, is looked up by a first address portion of an accessed address; a data storage section; a tag control section configured to, when the suspension-indicating section contained in the looked-up index indicates suspension, allow access relevant to the accessed address to wait, and when the suspension-indicating section contained in the looked-up index indicates non-suspension, compare a second address portion different from the first address portion of the accessed address to each of the plurality of tag addresses contained in the looked-up index, and detects a tag address matched with the second address portion; and a data control section. |

1. A cache memory, comprising:
a tag storage section in which one of a plurality of indexes, each index containing a plurality of tag addresses and one suspension-indicating section, is looked up by a first address portion of an accessed address; a data storage section configured to store each of data corresponding to the plurality of tag addresses for each of the plurality of indexes; a tag control section configured to, when the suspension-indicating section contained in the looked-up index indicates suspension, allow access relevant to the accessed address to wait, and when the suspension-indicating section contained in the looked-up index indicates non-suspension, compare a second address portion different from the first address portion of the accessed address to each of the plurality of tag addresses contained in the looked-up index, and detects a tag address matched with the second address portion; and a data control section configured to, when the suspension-indicating section contained in the looked-up index indicates non-suspension, select, from the data storage section, data corresponding to the tag address matched with the second address portion among the plurality of tag addresses contained in the looked-up index. |
