ELECTRICALLY ERASABLE PROM (EEPROM) VS. Renesas plan to have 100 to 150MHz MRAM at 90nm around 2010, and 200Mhz MRAM at 65nm around 2012. Thanks for the EEPROM Vs Flash info. Pages: [1] Topic: Speed of EEPROM.read() (Read 3718 times) previous topic - next topic. Flash memory is a type of EEPROM designed for high speed and memory density. Flash memory is a type of EEPROM designed for high speed and high density, at the expense of large erase blocks (typically 512 bytes or larger) and limited number of write cycles (often 10,000). Presently, flash memory is used in the portable storage of digital pictures with devices such as digital camera secure data cards, USB flash memory sticks, cellphones, pagers, and scanners. fkatzenb Guest; Speed of EEPROM.read() Oct 03, 2008, 01:16 pm. I haven't really decided yet, memory size will most likely dictate the frequency. This is because the address and data are sent to and from the chip one bit at a time using two or three wires. However, flash chips are too expensive on a per-byte basis to be used as mass storage devices. All; I am trying to reduce the amount of memory being used on my project. Go Down. Flash Memory vs SSDs. As such, flash drives based on this technology can store many gigabytes of data on a USB stick smaller than your thumb, which is how they earned the name “ thumb drives. DYNAMIC RAM (DRAM) VS… 10. However, this terms has sortof converged to mean a type of EEPROM that is optimized for large size and density, usually at the expense of large erase and write blocks and lower endurance. The difference is that a serial EEPROM typically has only 8 pins on the package. Serial MRAMs have the same SPI interface as Flash and EEPROM but with fast 40MHz clock speed and no write delays. > Speed of EEPROM.read() Print. EEPROM vs Flash Memory is always a debatable topic but do we understand each of them well enough to decide which one to choose for an underlying application. In this post, let’s try to focus on a common question which most of us have faced during our … Basically I want to periodically sample and store an averaged value on a 5 minute to 15 minute basis. Flash memory (or simply flash) is a modern type of EEPROM invented in 1984. Flash memory can be erased and rewritten faster than ordinary EEPROM, and newer designs feature very high endurance (exceeding 1,000,000 cycles). Flash is a type of EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROM sounds like a better choice for what I'm trying to do. "Flash" is more of a marketing term than a specific technology. A serial EEPROM is created with the same technology used in larger parallel EEPROMs. FLASH ... so designers typically use lower-cost serial EEPROM unless endurance or speed is a mandatory system requirement. Non-volatile memory : Non-volatile memory, nonvolatile memory, NVM or non-volatile storage is computer memory that can retrieve stored information even after having been power cycled (turned off and back on).
