  • Patent number: 11380376
    Abstract: An exemplary memory is configurable to operate in a low latency mode through use of a low latency register circuit to execute a read or write command, rather performing a memory army access to execute the read or write command. A control circuit determines whether an access command should be performed using the low latency mode of operation (e.g., first mode of operation) or a normal mode of operation (e.g., second mode of operation). In some examples, a processor unit directs the memory to execute an access command using the low latency mode of operation via one or more bits (e.g., a low latency enable bit) included in the command and address information.
