SDRAM chips have a burst mode that obtains the second and subsequent characters in 10 ns or less. DRAM (dynamic random access memory) chips for personal computers have access times of 50 to 150 nanoseconds (billionths of a second).

Webchip select activating the column decoder and the input and output buffers. write enable (W) The read or write mode is selected through the write-enable (W) input. A logic high on the W input selects the read mode and a logic low selects the write mode. The write-enable terminal can be driven from standard TTL circuits without a pull-up resistor. WebSPI interface is driven by SPI Clock to satisfy the Initial Access Time depending on the clock frequency; so, different numbers of dummy cycles are needed. For a constant …
Weband output enable (OE) LOW, with write enable (WE) HIGH. The chip drives I/O pins with the data word refer-enced by the input address. When chip enable or output enable is HIGH, or write enable is LOW, output drivers stay in high-impedance mode. All chip inputs and outputs are TTL-compatible, and opera-tion is from a single 5V supply. WebFeb 5, 2015 · Here is a typical timing diagram for an SPI peripheral, in this case a 2AA1024 1 Mbit serial EEPROM. In this case, the timing is for writing a byte to the EEPROM. As you can see, the chip select is brought low at the beginning of the 8-bit transfer and left there. (In general, it can be left low across as many bytes as needed to be read.)
