A random access memory including multiple state machines and selection circuitry. The multiple state machines include a first state machine and a second state machine, and possibly more state machines. The first state machine is configured to provide first signals to control the random access memory and provide first command operations and the second state machine is configured to provide second signals to control the random access memory and provide second command operations. The selection circuitry selects one of the multiple state machines. The selection circuitry conducts the first signals to select the first state machine and provide the first command operations and the selection circuitry conducts the second signals to select the second state machine and provide the second command operations.
