The structure of the memory, what are the types of storage structures?

The storage structure is:

(This set of storage units can be contiguous or discontinuous).

Example: Chains. Examples: arrays, chains.

Example: Clue tree.

4. Hashing. Storage: Scattered pure knowledge column storage, also known as hash storage, is a search technology that tries to establish a correspondence between the storage location of data elements and key codes.

Example: Stack (either sequential or random).

In the sequential storage, each storage space contains the information of the stored elements themselves, and the logical relationship between the elements is the sequential storage of the linear table simply calculated by the array subscript position, if the subscript position of an element stored in the corresponding array is i, then its predecessor element in the corresponding array is the subscript position of i-1, and its successor element in the corresponding array is i+1.

In a chained storage structure, the storage nodes contain not only the information about the elements themselves, but also the information about the logical relationships between the elements.

In the sequential storage of data, since the storage location of each element can be calculated simply, the time to access the elements is the same.

In the linked storage of data, since the storage location of each element is saved in its precursor or successor node, it can only be accessed by the pointer when its precursor node or successor node is accessed, and the time of accessing any element is related to the position of the element node in the chain storage structure.

d. Memory parts.

The main disadvantage of the storage medium that makes up the memory is the use of semiconductor devices and magnetic materials. The smallest unit of memory is a bistable semiconductor circuit or a CMOS tube or a memory element of a magnetic material that can store a binary**.

A memory cell is made up of several storage elements, and then a memory is formed by many memory cells. Memory structureIn the MCS-51 series microcontroller, the program memory and data memory are independent of each other, and the physical structure is also different.

A memory is a place where you can store several acres of early stance. It uses the level to store data, that is, it actually stores the high and low of the level, not the number 1234 that we are used to assuming.

A memory is like a small drawer, a small drawer has eight small grids, each small grid is used to store the "charge", the charge is transmitted or released through the wire connected to it, as for how the charge is stored in the small grid, we don't have to worry about it, you can think of the wire as a water pipe, the charge in the small grid is like water, then it is easy to understand. Each small drawer in the memory is a place where data is stored, and we call it a "cell".

There is a control line on each unit, I want to put the data into which unit, just give a signal to the control line of this unit, this control line will turn on the switch, so that the charge can flow freely, and there is no signal on the control line of other units, so the switch is not turned on, it will not be affected, so that as long as the control line of different units is controlled, different data can be written to each unit, and similarly, if you want to take data from a unit, you only need to turn on the corresponding control switch.

Memory is a memory device used to store information in modern information technology. The concept is very broad, there are many levels, in a digital system, as long as the binary data can be stored can be memory; In integrated circuits, a circuit with storage functions that does not have a physical form is also called memory, such as RAM, FIFO, etc.; In the system, storage devices with physical forms are also called memory, such as memory modules, TF cards, etc. The computer's full-profile information, including the input raw data, computer programs, intermediate and final run results, is saved in memory.
