Abstract

A data storage device with flash memory. The controller receives a mode selection command from a host. In response to the mode selection command, the controller sends a ready-to-transfer message to the host, to further receive a data out message from the host that is sent by the host in response to the ready-to-transfer message. The ready-to-transfer message and the data out message are UFS protocol information unit (UPIU) messages. The data out message is arranged to rewrite a first mode page setting among a plurality of mode page settings of firmware stored in the flash memory. In response to the data out message, the controller determines whether the data out message will change mode parameters which cannot be rewritten in the first mode page setting, to adopt or refuse new mode parameters issued through the data out message for the first mode page setting.

Claims20

Dependent claims

A data storage device comprising:

a flash memory storing a firmware, wherein the firmware comprises a plurality of mode page settings, and each mode page setting comprises a plurality of mode parameters;
and
a controller receiving a mode selection command from a host, wherein, in response to the mode selection command, the controller sends a ready-to-transfer message to the host, to further receive a data out message from the host that is sent by the host in response to the ready-to-transfer message:
wherein:
the ready-to-transfer message and the data out message are universal flash storage (UFS) protocol information unit (UPIU) messages;
the data out message is arranged to rewrite a first mode page setting among the plurality of mode page settings;
in response to the data out message, the controller determines whether the data out message will change mode parameters which cannot be rewritten in the first mode page setting;
when determining that the data out message will not change the mode parameters which cannot be rewritten in the first mode page setting, the controller adopts new mode parameters issued through the data out message for the first mode page setting;
and
when determining that the data out message will change the mode parameters which cannot be rewritten in the first mode page setting, the controller refuses to adopt the new mode parameters issued through the data out message for the first mode page setting.

A method for rewriting parameters applied in a data storage device which comprises a flash memory storing a firmware, the firmware comprising a plurality of mode page settings, each mode page setting comprising a plurality of mode parameters, and the method for rewriting parameters comprising:

receiving a mode selection command from a host;
in response to the mode selection command, sending a ready-to-transfer message to the host, to further receive a data out message from the host that is sent by the host in response to the ready-to-transfer message, wherein the ready-to-transfer message and the data out message are UFS protocol information unit (UPIU) messages, and the data out message is arranged to rewrite a first mode page setting among the plurality of mode page settings;
in response to the data out message, determining whether the data out message will change mode parameters which cannot be rewritten in the first mode page setting;
when determining that the data out message will not change the mode parameters which cannot be rewritten in the first mode page setting, adopting new mode parameters issued through the data out message for the first mode page setting;
and
when determining that the data out message will change the mode parameters which cannot be rewritten in the first mode page setting, refusing to adopt the new mode parameters issued through the data out message for the first mode page setting.
