Abstract
In a method for address table cache management, a first logical address associated with a first read command may be received. The first logical address may be associated with a first segment of an address mapping table. A second logical address associated with a second read command may then be received. The second logical address may be associated with a second segment of the address mapping table. A correlation metric associating the first segment to the second segment may be increased in response to receiving the first logical address before the second logical address. The first logical address and second logical address may each map to a physical address within the address mapping table, and a mapping table cache may be configured to store two or more segments. The mapping table cache may then be managed based on the correlation metric.
