Executing parallel operations to increase data access performance

Abstract

Techniques are described for increasing data access performance for a memory device. In various embodiments, a scheduler/controller is configured to manage data as it read to or written from a memory. Read or write access is increased by partitioning a memory into a group of sub-blocks, associating a parity block with the sub-blocks, and accessing the sub-blocks to read data as needed. Write access is increased by including a latency cache that stores data associated with a read command. Once a read-modify write command is received, the data stored in the data cache is used to update the parity block. In a memory without a parity block, write access is increased by adding one or more spare memory blocks to provide additional memory locations for performing write operations to the same memory block in parallel.
