Memory Cards & Modules definition
Memory Cards are electronic storage devices used on a pc board for storage or transferring digital information that can be easily inserted and removed.
Types of Memory modules
Types of memory module include: TransFlash Memory Module. SIMM, a single in-line memory module. DIMM, dual in-line memory module. Rambus memory modules are a subset of DIMMs, but are normally referred to as RIMMs. SO-DIMM, small outline DIMM, a smaller version of the DIMM, used in laptops.
DRAM Modules
DRAM modules are circuit boards that include a collection of dynamic random access memory (DRAM) chips.
DRAM chips are single-transistor dynamic memory cells that store bits in a row-and-column addressable configuration using capacitors. DRAM chips are a sort of random access memory (RAM) that has to be charged or refreshed on a regular basis in order to preserve data.
A DRAM module requires a power source to preserve its data because it is a dynamic memory device. DRAM modules employ volatile memory in this fashion. Static memory, on the other hand, does not need the replacement of the capacitor. Data is retained in flash memory regardless of the power source.
Depending on their properties, different types of DRAM modules are available, such as FPM (fast page mode), EDO (extended data out) and SDRAM (synchronous DRAM).
Example for products of DRAM modules as the following: Micro Technology Inc. MT16HTF51264HZ-800C1 Memory Module, ATP Electronics, Inc. AL12P72L8BKK0M, ATP Electronics, Inc. AW12M64B8BLK0MW, Advantech Corp AQD-SD3L2GN16-SQ, Wintec Industries 96D2-1G667NN-TRL, Swissbit SFUI2048J1AB1TO-I-GS-2AP-STD and Apacer Memory America 78.D2GF2.4010B Memory Module.
