Abstract
Systems and methods are included for determining a presence of an upcoming reading field during a write mode of a storage device, and initiating a read-while write (RWW) mode of the storage device in response to the sensed reading field. Initiating the RWW mode comprises warming up the reader circuitry, generating a signal in response to an end to the write operation, and activating reader bias current in response to the generated signal.

1-20. (canceled)
A device configured to enable a read while write (RWW) function in a non-volatile storage device, comprising:
- preamplifier circuitry;
- serial interface circuitry coupled to the preamplifier circuitry;
- and
- a controller configured to:
- transfer configuration data packets to the preamplifier using the serial interface circuitry during a first time period;
- use one or more output pins of the serial interface circuitry to enable the function during a second time period in which the configuration data packets are not transferred;
- initiate a warm-up of read circuitry during a write mode of the memory device;
- end an alternating write signal at a predetermined amount of time after initiating the warm-up;
- and
- use a serial data port of the serial interface circuitry to transmit a reader bias current enable signal after ending the alternating write signal.
