What is a SIM Card? A SIM (Subscriber Identity Module) card is an integrated circuit card used in GSM systems to identify mobile users. It allows GSM networks to recognize subscribers, and the same SIM card can be used across different phones. Without a SIM card, a GSM phone cannot connect to the network. In […]

Introduction to NOR Flash and NAND Flash NOR Flash Intel first developed the Nor Flash technology in 1988. Nor Flash is characterized by on-chip execution (XIP, eXecute In Place), and its reading is similar to the random reading form of our common SDRAM. Users can directly run the program loaded on the Nor Flash The
What is EPROM? EPROM, the abbreviation of “Erasable Programmable Read-Only Memory”, is a non-volatile storage chip that retains data even after power failure. It’s invented by Israeli engineer Dov Frohman. It is a group of floating gate transistors that are individually programmed by an electronic device that supplies a higher voltage than is commonly used

Do you hear about flash memory before? What is the difference between NOR and NAND? If you’ve been keeping tabs on the latest developments in computer hardware, you might have heard about these acronyms at least once. However, if you aren’t sure what they mean or how they work, this article is for you. Read
One Time Programmable (OTP) memory is non-volatile, meaning it retains its data when powered off. It is a special type of read-only memory that can only be programmed or written to once. Once this memory has been programmed or written, it cannot be rewritten again without special equipment and procedures. Programming OTP memory requires specialized
