What is synchronous SRAM?How is it different from asynchronous SRAM?

Static random access memory(SRAM)itself is a kind of storage technology that loses data when power is off,but does not need to be refreshed when working.Each memory cell in it usually needs 6 transistors,which also determines its characteristics of high production cost and small capacity.But in terms of speed,SRAM has always had an advantage.
 

SRAM is mainly divided into synchronous and asynchronous types.Asynchronous SRAM controls read and write operations by internally generated clock signals.Although the power consumption is low,the timing control is difficult and the read and write speed is slow.Synchronous SRAM works with a unified external clock signal coordination circuit,and all operations are strictly aligned with the clock edge-address and control signals are latched on the rising edge of the clock,and data is read or written on the subsequent clock edge.
 

Advantages of EMI high-speed synchronous SRAM

The high-speed synchronous SRAM memory introduced by EMI is just to solve the speed problem of traditional asynchronous SRAM.After receiving the read-write instruction,the synchronous SRAM must refer to the edge of the external clock signal to initiate the operation.This"synchronization"mechanism brings several obvious benefits:

①system clock synchronization:the synchronous SRAM memory works in the same clock domain as the CPU or FPGA,without extra waiting time.

②Faster speed:Synchronous SRAM is suitable for high-speed network equipment,high-end communication chips,FPGA cache and other time-sensitive application scenarios.

③Improvement of data transmission efficiency:Through pipeline architecture,address transmission can be completed in one clock cycle,and data can be output in the next cycle,thus effectively improving bandwidth.
