Systems, devices, and methods for password protection of defined spaces in a memory device. The method includes receiving a data block from a host. The data block includes a user-defined current password, a user-defined new password, a password length of the current password, a password length of the new password, and a user-defined address range field including start and end addresses of a defined space in the memory device. The method further includes matching password lengths of the user-defined current password and a current password length of a current password for the defined space already stored in the memory device. The method also includes comparing the user-defined current password and the current password of the defined space. The method further includes replacing or resetting the current password of the defined space with the user-defined new password based on a result of the matching and a result of the comparing.

Methods and systems for password protection of defined spaces within a memory card

A method and apparatus for sustaining performance of a data storage device by predictively determining resource needs and executing processes to meet those needs before the resources are actually needed. According to certain embodiments, a controller collects commands coming from a host and provides these to a machine learning model such as a recurrent neural network (RNN). The RNN is trained using this data, and output of the trained model is used to predict future commands. As future commands are developed by the RNN, resource allocation processes such as garbage collection may be initiated prior to the actual need, during times when processing cycles in the data storage device are available. By operating the garbage collection when the device has available processing may mitigate transition to an urgent mode.

Data storage device having predictive analytics

Systems, devices, and methods for resetting a current password of a memory device or a memory card system. The method includes receiving a data block including a content field, a combined password length of a user-defined current password and a new password, and a user-defined password length of the new password. The content field includes the user-defined current password and the new password. The method also includes determining a system calculated password length of the new password based at least on the combined password length and a length of the current password. The method further includes matching the system calculated password length and the user-defined password length and comparing the user-defined current password with the current password. The method also includes replacing or resetting the current password with the new password based on a result of the matching and a result of the comparing.
