Ram Chip Diagram. Table 10 shows the address range of the two chips. To write to memory we set wr 1.
Required size is 512 x 8 512 x 8 2 9 x 8 therefore 9 bit address is required. The block diagram of a ram chip is shown in fig. The ce pins are.
Wr selects between reading from or writing to the memory.
Ram chips are available in a variety of sizes and are used as per the system requirement. Rom chip rom can only read the data bus can only be in an output mode. It has four banks. Dynamic random access memory dram chips are single transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns.
