ROM: Unlike the RAM, the data present in the ROM cannot be changed thus being a non-volatile (it will always keep its contents regardless whether there’s power or not). – Direct Rambus DRAM (DRDRAM) – It considerably faster than the DRAM with an access speed of less than 20 nanoseconds. – Static RAM (SRAM) – Its access time is less than 60 nanoseconds. Its access time normally ranges from 60 to 70 nanoseconds. – Dynamic RAM (DRAM) – The maintenance of its state will always depend on the presence of electricity. These types of computer memory can be classified further as: A higher RAM performance normally translates to a higher performance of the computer system. Data in computer RAM can be accessed in order as long as it has been loaded. Therefore the co-ordination between these types of computer memory plays a significant role in computer operations. The information must be loaded in the RAM so that the processor can access it. Processors normally access information in a given order.
RAM: This is the main memory of any computer systems. Since the invention of computers, different types of computer memory have invented to achieve high levels of efficiency. Some have the ability to store data permanently while others lose all their data as soon as they lose power it all depends on the type of computer memory being used. When choosing a computer memory, some of the factors which must be put into consideration include the speed at which data can be stored and accessed besides the capacity of the memory location. There are different types of computer memory which may be classified according to how they store data, accessibility etc. The operating systems, software, user documents etc. The best thing about the CDROM memory is that they are very durable, especially when compared with all other types of memory.Ĭomputer memory is a location in which various data is stored in a computer system. However, instead of the head and arm, a laser light writes and reads the information on the CDs and DVDs to interpret it and display them in the monitor. These types of computer memory works like records and hard drives. These are the types of computer memory that are permanent and portable. These tape drives are mostly used by medium to large organizations as they offer long term and stable storage. They have ribbons and spools, where the data and information you would like to store are saved with the ribbon’s polarity. Tape drives are types of computer memory that work like tapes or audio cassettes. The fastest of the flash memories can only read up to 22 megabytes every second. At present, the biggest flash memory drives can only hold up to 32 GB of data.

These are very small and portable devices therefore not much hardware is available, hence the small storage space. They cannot, however, keep as much data and information like the hard disk drive.
Even when there is no power, the information and data saved in them are kept safe and secure. Flash memories are types of computer memory that works like RAM but are stable. However, all the information and data stored here are short term as after they are processed the RAM frees itself so that more information can be processes by the CPU after.įlash Memory. RAM work really fast as they are the ones who bring the information to the brain to be processed. Since they are electronic, there are no arms, heads and spinning involved. These types of memory work reversely like tapes. These are electronic types of computer memory that accesses any information any time. The largest hard drives available these days are as big as 2 terabytes and can store information up to 70 megabytes every second. When the head is at a certain location, data and information are either being written or deleted from that area of the hard drive.
They are spinning platters that have arms with head to touch the different parts of it. They can store the data and information long term as this is where you store your music, games, documents, and the like. The hard disk drives are among the most common types of computer memory. No matter how you want to use your computer, you can surely be able to enjoy them better if you have a better type of memory in it. There are many different types of computer memory that can be used in different technologies. These computers work by the help of computer memory as they safe keep the data while they have not been processed yet. What are the different types of computer memory? Computers are very important parts of our daily lives.
