Abstract
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.
