Quick Summary

Synchronous DRAM (SDRAM) is a type of random-access memory (RAM) that synchronizes with a computer's system clock. This synchronization allows for more efficient data transfer compared to earlier asynchronous DRAM.12

SDRAM became the standard in the 1990s and was later succeeded by DDR-SDRAM (Double Data Rate SDRAM), which further improved efficiency by transferring data twice per clock cycle. Subsequent generations like DDR2, DDR3, DDR4, and DDR5 have continued to enhance speed, capacity, bandwidth, and power consumption, with DDR5 being particularly beneficial for demanding applications like AI and gaming.2
