Abstract
A memory device stores data for a host device. In one approach, a method includes: selecting, by the memory device, a first mode of operation for a host interface that implements a communication protocol for communications between the memory device and the host device. The host interface is configured to implement the communication protocol using a mode selected by the memory device from one of several available modes. In response to selecting the first mode, resources of the memory device are configured to customize the host interface for operation in the first mode.
Claims19
An apparatus comprising:
- a temperature sensor and an accelerometer configured in a vehicle, the temperature sensor and accelerometer to determine the vehicle is in crash;
- a host interface having a plurality of resource configurations each corresponding to a different mode of operation of the host interface, wherein the host interface is configured to receive a stream of commands from a host device, and wherein host interface signals are used to transmit read data and write data;
- at least one processing device;
- and
- memory containing instructions configured to instruct the at least one processing device to:
- select, based on signaling from the temperature sensor and accelerometer, a first mode of operation of the host interface;
- in response to selecting the first mode, configuring the host interface to a first resource configuration of the plurality of resource configurations, the first resource configuration corresponding to the first mode of operation;
- power-up with the host interface in a second mode of operation, wherein the second mode of operation is a read/write mode;
- analyze the stream of commands while operating in the read/write mode;
- dynamically change, based on analyzing the stream of commands, a number of the signals used to transmit the read data in the read/write mode, and a number of the signals used to transmit the write data in the read/write mode;
- and
- after power-up, change the mode of operation of the host interface to a third mode of operation, wherein the third mode is a write-only mode or a read-only mode, wherein changing the mode of operation to the third mode is implemented in response to receiving a command from the host device.
