Synchronous Dynamic Random Access Memory


synchronous dynamic random access memory

[¦siŋ·krə·nəs dī‚nam·ik ‚ran·dəm ′ak‚ses ‚mem·rē] (computer science) High-speed memory that is controlled by the system clock and can run at bus speeds up to 100 megahertz. Abbreviated SDRAM.

Synchronous Dynamic Random Access Memory

(storage)(SDRAM, Synchronous DRAM) A form of DRAM whichadds a separate clock signal to the control signals. SDRAMchips can contain more complex state machines, allowing themto support "burst" access modes that clock out a series ofsuccessive bits (similar to the nibble mode DRAM).
