Memories and methods for performing vector atomic memory operations with mask control and variable data length and data unit size

A memory, comprising:

• operation logic configured to receive read data from a memory store, wherein the read data is associated with a command packet, and configured to further receive an operand from the command packet, and to perform an atomic operation on the read data and the operand in accordance with a command control signal and a configuration control signal, the operation logic comprising:
• a first selector circuit to configure the read data in accordance with the configuration control signal and provide the configured read data to an operation circuit,
• the operation circuit configured to receive the configured read data and the operand, and to perform the atomic operation on the configured read data and the operand in accordance with the command control signal to generate a resultant, and
• a second selector circuit configured to receive the configured read data from the first selector circuit and the resultant from the operation circuit and configured to forward first data to a packet assembler for forwarding on to a component external to the memory, and wherein the second selector circuit is further configured to forward second data to the memory store, wherein the first data is a first combination of portions of the resultant and portions of the read data, wherein the second data is a second combination of portions of the resultant and portions of the read data determined based on configuration information from the command packet, and wherein the first data is different than the second data.
