This Product Selection Guide contains information to help select products in the Memory category on DigiKey.com
Memory is a semiconductor device that is used as data storage device on an integrated circuit. These devices are available in several formats CBRAM, DRAM, EEPROM, EERAM, EPROM, Flash, FRAM, NVSRAM, PCM (PRAM), PSRAM, RAM, and SRAM in either Non-Volatile or Volatile. These devices memory sizes range from 64 b to 6 Tb with the interface being I2C, MMC, Parallel, eMMC, Serial, Single Wire, SPI, UFS, Xccela Bus, and 1-Wire.
SelectionCharacteristics
DigiKey Programmable: For verified products, DigiKey can program/flash your compiled code or configuration variables prior to shipping. For unverified products, please inquire with ProgCent.Techs@digikey.com.
Memory Type: The fundamental characteristic of the memory cells.
Memory Format: The specific technology or architecture used in the memory cells.
Technology: The specific underlying technology or architecture used in the memory cells.
Memory Size: The amount of memory available on the device.
Memory Organization: The specific arrangement and structure of the memory cells.
Memory Interface: The communication protocol used to access or transfer data to and from the device.
Clock Frequency: The frequency at which the memory device operates.
Write Cycle Time - Word, Page: The time it takes to perform a write operation on a specific unit of data or a group of data.
Access Time: The time required for valid data to become available after issuance of a read command.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type : Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
