It mainly refers to those calculators that can record formulas and text information.
A calculator generally consists of a combinator, controller, memory, keyboard, display, power supply and some optional peripherals and electronic accessories, either manually or mechanically. The combinator and controller of the low-grade calculator are simple serial operations by digital logic circuits, and their random access memory is only.
One or two units for cumulative storage. High-grade calculators use microprocessors and read-only memory to implement a variety of complex computing programs, and have more random memory units to store input programs and data. The keyboard is the input part of the calculator, which is generally contact or sensor.
In order to reduce the size of the calculator, one button often has multiple functions. The display is the output part of a calculator, such as a light-emitting diode display or a liquid crystal display. In addition to displaying the calculation results, there are also frequent overflow indications, error indications, etc.
The power supply of the calculator uses an AC converter or a battery, and the battery can be recharged with an AC converter or solar converter. In order to save electricity, the calculators are LSI made by CMOS process (see Complementary Metal-Oxide-Semiconductor Integrated Circuits) and are equipped with an automatic power-off circuit that does not operate at the timed time. The peripherals that can be used for the calculator include micro printers, cassette drives, and magnetic card drives.
Different computers serve different purposes.

The so-called storage function refers to calculators such as mobile phones and electronic dictionaries, which can store some data.
The names of "calculators" on the market are basically professional calculators, which can only be used for scientific calculations and cannot store information. (M and independent storage unit ABC and so on can only store numbers, not counting with storage function).
Use the calculator's storage functions as follows:
1. First, enter the formula you want to calculate in the calculator, such as 7 8 15.
2. After the calculation result is displayed, it will be displayed on the screen, then press the ft button, then press the sto button, and then press the A button to the top of the red capital letters. This process saves the results on your computer.
3. Then press the alpha button, then press the A button. The result here is equal to the result stored in the previous step. This process is a copy of the previous step, and the result is a 3 18.

It is a function that can save the results of previous calculations and call them up for use in future calculations.

Calculators don't have a memory function, and it's not the same as calculators don't have a storage function.
Some standard calculators have a digital storage function, which includes four buttons: MRC, M-, M+, and MU.
After typing the number, press MS to read the number into memory, and then no matter how many steps are performed, you only need to press MR once to read the previously stored number, press MC to remove the number from memory, or press twice to calculate the interest rate, 2000 [mu] 20% = 2000 (1-20%) = 2500, 2000 [mu] [ 20% = 2000 (1 + 20%) = .

If the calculator has "Ctrl+M+", it means that the calculator has a storage function, and if it has an M+ function, it means that the calculator has a storage function.
Calculators without storage function refer to scientific calculators, which can perform operations such as squares, logarithms, exponents, and multiplications, which are of great help to mathematics work or number sidebanding majors.
A calculator with a storage function can store some data, this kind of calculator can calculate some complex data, and it can also measure some data, and not only that, it can also store data.
The calculator we use in our daily life is a simple calculator, which can only do addition, subtraction, multiplication and division operations.
Commonly used keys in simple calculators include clock, which is an alarm button, and you can press the clock button on the calculator to announce the time in real time, in addition to setting an alarm clock. If there is no voice announcement function on the calculator, then there is no clock button on the calculator.
There is no clock button in the scientific calculator, and it cannot broadcast the time, let alone set an alarm. However, the scientific calculator can calculate super large numbers, and also has functions such as overflow indication and error indication, which can better help users deal with numbers.
