Translation of "Memory backup" in German

This is called backup memory 6 b below.

The ferroelectric memory is therefore integrated onto the semiconductor surface as a backup memory so to speak.

By contrast, the error results backed up in the backup memory 6 a are generally not erased.

By way of example, the backup memory 6 a can store a maximum of ten (i.e. N=10) error results.

As stated, the corresponding values are in this case stored in the backup memory 9.

The strip memory M can be loaded on program start via the output of backup memory SD.

The internal memory supports the backup of recorded clips to FTP server or Google Drive.

The backup memory ensures that it is not possible to falsity the value amount settlement with the Post Office as a result of servicing or tampering.

A franking machine comprises, in addition to a main memory, a backup memory which receives the content of the main memory upon opening the casing or a casing cover of the franking machine.

Thus, when storing the contents of the main memory 6, it is necessary to carry out storage in the backup memory 9 in accordance with the same subdivision.

The unit MMI is in communication with a unit KI that is in turn connected to the backup memory HD1 and to the IEC bus that connects the function modules.

The apparatus according to claim 2, wherein the user accounts are further subdivided into subaccounts, and the interchange of memory contents between said main memory means and said backup memory means takes place in accordance with such further subdivision.

At the end of an operating cycle, i.e. when the motor vehicle ignition is turned off (which is notified via the ignition signal line I), a backup copy of the content or of a part of the content of the error result memory 7 a is made, in accordance with the invention, in the (non-volatile) backup memory 6 .

In this context, all the error results (F, t) obtained during the elapsed operating cycle are backed up in a section 6 a of the backup memory 6 .

In this case, the error result (Fn, tn) is not added to the backup memory 6 a as a new error, but instead the error result already entered is updated with the new error detection time tn.

In addition to the backing up of error results (in the backup memory 6 a) and/or preset values and also possibly control parameters (in the backup memory 6 b) which is described here, the backup memory 6 may also store other values which need to be available by reading in the aforementioned manner after the motor vehicle control unit 1 has been isolated from the vehicle electrical system 11 .

However, the check to determine whether the memory cells or memory cell areas which are currently to be written to or read from need to be replaced with backup memory cells or backup memory cell areas and the replacement of the unusable memory cells or memory cell areas are associated with a not inconsiderable level of complexity and/or limit or reduce the speed at which data can be written to the memory device or can be read therefrom.

The non-volatile, writable backup memory provides a storage medium in which a loss of data occurs neither when the control unit is isolated from an operating voltage supplying the control unit with power nor if the monitoring result memory is intentionally erased, for example by the workshop.

The monitoring results (an individual monitoring result may also be involved) previously transferred to the non-volatile backup memory can thus be reconstructed by reading the non-volatile backup memory once the control unit has been sent to the manufacturer.

Preferably, the monitoring result stored in the monitoring result memory is in each case transferred to the non-volatile backup memory at the end of an operating cycle of the control unit.

Since the backup memory 6 may also comprise solely the section 6 a, it is called backup memory 6 a below for the sake of simplicity.

An appropriately large memory capacity N in the backup memory 6 a permits the loss of error results to be virtually precluded, however.

Transfer can thus take place, for example, in each case at the end of an operating cycle in the form of an update to the content of the backup memory 6 b.

The selection device AE could, of course, also receive the information about the location of the backup memory cells or backup memory cell areas to be used in another way.

Therefore, and because the information about the location of the memory cells and memory c ell areas to be replaced is already supplied to the selection device before replacement of the memory cells or memory cell areas is initiated by the output signal from the logic unit L, the need to replace memory cells or memory cell areas which cannot be written to or read from properly with backup memory cells or backup memory cell areas can be established and the replacement implemented without any, or at any rate without any significant, delay in writing to or reading from the memory device.
