1.	Which refresh technique is useful for low power consumption?(a) Software refresh(b) CBR(c) RAS(d) Burst refreshThe question was asked in unit test.My doubt stems from DRAM Refreshing Techniques topic in chapter Memory Systems of Embedded Systems
Answer» The correct choice is (b) CBR The explanation is: CBR that is, CAS before RAS refresh is the ONE which is commonly used. It has low power consumption quality because it does not have ADDRESS bus and the buffers can be switched off. It is worked by using an internal address counter which is STORED on the memory chip itself and this can be INCREMENTED periodically.
