Embodiment Construction

[0060] figure 1 It is a schematic diagram of a device for accumulating and storing respective access times of a plurality of word lines (word line, WL) in a memory module 100 (such as a dynamic random access memory) according to an embodiment of the present invention, wherein the The device may include at least a portion (eg, a portion or all) of the memory module 100 . For example, the device may include a local memory architecture of the memory module 100 . As another example, the device may include a combination of the local memory architecture and associated control mechanisms. As another example, the device may include the entire memory module 100 .

[0061] Such as figure 1 As shown, memory module 100 may include at least one memory bank (eg, one or more memory banks) such as memory bank 110 . The memory bank 110 may include a plurality of storage cells 110SC such as (K*(M+N)) including (K*M) ordinary (ordinary) storage cells 110A and (K*N) extraordinary (extra...

Abstract

A method and apparatus for accumulating and storing respective access counts of a plurality of word lines in a memory module are provided. The method may include: within a memory bank positioned in the memory module, providing a plurality of extraordinary storage cells coupled to the plurality of word lines; and utilizing the plurality of extraordinary storage cells to accumulate and store the respective access counts of the plurality of word lines, wherein multiple sets of extraordinary storage cells in the plurality of extraordinary storage cells correspond to the plurality of word lines, respectively. The method and the related device can ensure that the memory module can properly operate under various conditions, and can simultaneously generate or update the word line access times during the daily use period of the memory module.

Description

technical field [0001] The present invention relates to memory management, especially to a method and apparatus for accumulating and storing the respective access times of a plurality of word lines in a memory module, for example by means of The local memory architecture of this memory block. Background technique [0002] According to related technologies, a memory such as a dynamic random access memory (Dynamic Random Access Memory, DRAM) can be used to store user data. Certain problems arise when it is necessary to detect the number of word line accesses. For example, since there will be thousands of word lines in the memory, implementing thousands of counters corresponding to the thousands of word lines will generally increase the associated costs, especially, these thousands of counters will occupy a certain amount of time in a chipset. A ratio (eg, a percentage) of chip area. As the storage capacity will increase with the research / development process, the total numbe...
