Most of the ones designed for "master" programming (not just duplication) hook to a PC in some way. Without either of the two, our devices wouldn’t perform the way they do now.I can't find much information about your model.
RAM and ROM are both highly essential to the proper functioning of our computer.

The main drawback of ROM is that due to it being non-volatile, we are unable to update the firmware even in cases of malfunctioning where every chip will have to be checked and replaced one after another. Mask ROM – It is the data that has been written during the manufacturing of the memory chip. Programmers can thus test the device multiple times before finishing the product. Electrically Erasable Programmable ROM (EEPROM) – Data on this non-volatile memory chip can be electrically erased using field electron emission repeatedly. Erasable Programmable ROM (EPROM) – Firmware can be re-written by the programmer, however, the erasing needs a high-intensity UV light, making it difficult anyways.ģ.
Programmable ROM (PROM) – It is the form of data that is non-volatile and written after the chip has been manufactured.Ģ. The different types of ROM available are- PROM, EPROM, EEPROM and Mask ROM.ġ. ROM can store only several megabytes of data so no computer will be able to function on just ROM. Since it is non-volatile it is reliable and its contents can be easily verified. Data stored here cannot be modified under any conditions which makes it non-volatile. Even after power is removed from chips it doesn’t delete the data recorded. It has pre-recorded data and is used to boot the computer. ROM is used to store files permanently for its functions.

It can also be used to hold software for basic processes of utilities and to read and write to peripheral devices. It is important for the BIOS(basic input/output system) and can also be used for standard data management. Read-only memory is necessary to provide instructions to the various hardware devices components present. They are used externally to microprocessors on the motherboard and store a bit of data using a pair of transistors and capacitors which constitute a DRAM memory cell. Dynamic RAM (DRAM) is slower and cheaper as compared to SRAM. It is much faster and the cost of production is high.Ģ. Static RAM (SRAM) is used as a cache memory of the microprocessor chip.
RAM can be classified into two main types: SRAM and DRAM.ġ. RAM chips can store multiple gigabytes of data. It stores files required temporarily and then deletes them once the PC shuts down. RAM can be read and changed in any order and typically used to store working data. It is what allows us to switch from one task to another mid-way and be able to go back to it when required. Just as the name suggests, for RAM the usage and access of memory is random because the microprocessor needs to write changing data rapidly. RAM is what allows the users to perform everyday tasks and handle various experiences. Random-access memory provides the working memory of the system and with better RAM we needn’t access slower disk arrays. Stores data that is needed to bootstrap the computerĪccess time is very short as data frequently required is stored here.ĭata is from ROM is copied to RAM so as for CPU can access it. Memory is used to store data that CPU needs for current instruction processing RAMĭata can be read, accessed, erased or modified. The table below provides a simplified understanding of how RAM and ROM differ from each other. It is important to know what is RAM and ROM and enlist the comparison between them to get a better understanding of our memory system.
More memory is never unhealthy so systems with better RAM are preferred most of the time. This is important as memory defines the overall performance and speed of our system. The memory specifications are given the utmost importance while choosing the best computer for us. They are built with two main types of memory RAM and ROM. Similarly, our computers also have different types of memory systems. they are just quick to think or react to a change. Now some of us are said to have a sharper memory i.e.
