Alza Days - Computer RAM
- The campaign runs from May 4 to May 18, 2026 (“Campaign”).
- The list of products currently available in the Campaign (“Products”) can be found on this website below.
- A Product is considered purchased at a discounted price as part of the Campaign only once the order has been confirmed by Alza and the payment has been completed by the customer. Simply placing the Product in the cart does not constitute a purchase. If the Buyer selects cash-on-delivery payment, submitting the order to Alza within the Campaign period is sufficient, but the discount will only be valid upon successful payment upon delivery.
- Alza reserves the right to limit the number of Products a single buyer may purchase during the Campaign for certain items. Should such purchase limits apply, Alza's system will automatically prevent buyers from adding more Products to their cart than the permitted purchase quantity for the duration of the Campaign.
- Available stock of select Products will be allocated among consumers in the Czech Republic, Slovakia, Austria, Hungary, and other countries served by Alza.
- Discounts on Products are valid only during the Campaign period or while supplies last. Alza reserves the right to change the selection of discounted Products at any time during the Campaign.
- The general terms and conditions of the Campaign can be found here.

RAM system memory
The RAM memory is an essential part of every computer. The exact term is RWM - RAM (RWM - Read Write Memory, RAM - Random Access Memory). It refers to the fact that this type of memory can be repeatedly written to and read from and can also be accessed randomly. The capacity and speed of the installed memory greatly affects the performance of your computer. A computer can use several memory modules at once. These hold all the instructions that the computer's processor executes, i.e. the data of all programs you use. The data is not stored permanently in the RAM memory. Each time the computer shuts down, the whole memory is completely erased. The system memory is used for this purpose because it is much faster than a standard hard drive and it provides significantly shorter access time. This ensures lightning-fast data transfers between the memory and the processor. Generally speaking, the more RAM you have, the better performance you get.
The history of operating memory is quite rich. During a relatively short period of time, a large number of technologies were tried and used. For example, in the beginning of its evolution, system memory was made of ferrite. In the 1950s, magnetic drum-shaped memory modules were made. Nowadays, DIMM memory (Dual Inline Memory Module) uses modern semiconductors.
Types of operating memory
System memory can be divided into many different types. Desktop computers and laptops use essentially the same type of memory, but it still differs in dimensions. Most computers and laptops use the DDR (Double Data Rate), DDR2 (currently the most common) or the newest DDR3 memory. These share the basic architecture, but later generations offer better performance. The DDR, DDR2 and DDR3 are not mutually compatible. Therefore, it is necessary to carefully choose what type of memory to buy. When choosing a new memory module, take into consideration what types, capacities, and frequencies are supported by your motherboard.
Other types of memory
There are many other devices labeled as memory. These have, however, a completely different purpose. Apart from RAM, there are memory banks (HDB), memory cards (for data storage, for example in phones), and portable memory sticks (used to transfer data between computers).
