By the aid of the method and the device in the technical scheme, a function of detecting related and associated errors in pressure test for the memory is realized by means of circularly traversing simple steps such as content modification and backtracking reading verification when the internal memory is detected. Accordingly, the stability and related performances of the memory are guaranteed.
Description
Technical field
The present invention relates to the detection technique of computer system, be specifically related to a kind of internal-memory detection method and device.
Background technology
Along with the fast development of current mobile storage technology and the high speed in mobile storage market enlarge, the consumption of various storeies increases rapidly, and the demand in market has expedited the emergence of research and development, production, the application enterprise of large quantities of various storeies.Be to guarantee chip work reliably and with long-term, these enterprises need carry out high speed and test carefully storer before product export, therefore, and the ten minutes necessity that just seems of the research of Test Algorithms for Memory efficiently.
No matter the test of which kind of type memory; It not a foolproof problem; Can not only each storage unit of memory inside be tested one time successively and just draw conclusion; This is because the change of each storage unit all might influence the variation of other unit of memory inside, particularly can cause the variation of adjacent cells, and this situation usually takes place again.
Common memory pressure method of testing can travel through memory headroom at present, but means of testing is single, can not detect this associated tape error of internal memory, and promptly a location contents changes the variation that whether can cause adjacent cells.Present situation in cut-throat competition is descending us not merely will be concerned about the function of storer, and we are the stabilities that under identical functions, compare with product in the time of more.Concerning storer, detect its stability like this and just shown its importance through pressure test.
Summary of the invention
The technical matters that the present invention mainly solves is, a kind of internal-memory detection method and device are provided, and solved when internally depositing into the row test, can't detect the problem of associated tape error in the internal memory simultaneously, guarantees the performance of storer.
The present invention provides a kind of internal-memory detection method, specifically may further comprise the steps:
In memory headroom, choose a storage unit as first address space;
Revise the memory contents of first address space;
Choose with the first address space adjacent memory unit as second address space;
Whether the content that detects second address space is former memory contents;
If, choose storage unit again as first address space according to preset rules, all be selected as first address space until all storage unit.
Further, revise before the memory contents of first address space, also comprise: whether the content that detects first address space is former memory contents, if then continue execution in step.
Further, before whether the content that detects first address space is former memory contents, also comprise: in first address space, preset first test data.
Further, revise the memory contents of first address space, be specially: the memory contents of first address space is revised as the pairing radio-minus-one complement form of said memory contents.
Further, in memory headroom, choose a storage unit as first address space, be specially: the storage unit of choosing the lowest order address is as first address space.
Further, choose storage unit again as first address space according to preset rules, be specially: pairing storage unit is as first address space after being chosen at the address value that increases storage unit.
The present invention also provides a kind of internal memory pick-up unit, has specifically comprised:
Address space is chosen module; Be used for choosing a storage unit as first address space at memory headroom; From memory headroom, choose the first address space adjacent memory unit as second address space according to preset rules afterwards, and will choose the result and send information to the content read module;
The content detection module, whether the content that is used to detect said second address space is former memory contents, if then send information to address space and choose module;
The content modification module is used to revise the memory contents of said first address space, and sends information to address space and choose module.
Further, the content detection module also is used for: whether the content that detects first address space is former memory contents, if then send information to the content modification module.
Further, the internal memory pick-up unit also comprises: the content preset module is used for presetting first test data at first address space.
Further, revise the memory contents of first address space, be specially: the memory contents of first address space is revised as the pairing radio-minus-one complement form of said memory contents.
Further, the described storage unit of in memory headroom, choosing is specially as first address space: the storage unit of choosing the lowest order address is as first address space.
Further, choose storage unit again as first address space according to preset rules, be specially: pairing storage unit is as first address space after being chosen at the address value that increases storage unit.
Through technical scheme of the present invention; When carrying out the internal memory detection; Read this several steps searching loop such as checking through simple content modification, rollback and realized in the memory pressure test, detecting the function of associated tape error, thereby guaranteed the performance of storer.
