W9825G6CH Notes: 1. Operation exceeds "ABSOLUTE MAXIMUM RATING" may cause permanent damage to the devices. 2. All voltages are referenced to VSS 3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the minimum values of tCK and tRC. 4. These parameters depend on the output loading conditions. Specified values are obtained with output open. 5. Power up sequence is further described in the "Functional Description" section. 6.
W9825G6CH OPERATION MODE Fully synchronous operations are performed to latch the commands at the positive edges of CLK. Table 1 shows the truth table for the operation commands.
W9825G6CH FUNCTIONAL DESCRIPTION Power Up and Initialization The default power up state of the mode register is unspecified. The following power up and initialization sequence need to be followed to guarantee the device being preconditioned to each user specific needs. During power up, all Vcc and VccQ pins must be ramp up simultaneously to the specified voltage when the input signals are held in the "NOP" state. The power up voltage must not exceed Vcc +0.3V on any of the input pins or Vcc supplies.
W9825G6CH Burst Read Command The Burst Read command is initiated by applying logic low level to CS and CAS while holding RAS and WE high at the rising edge of the clock. The address inputs determine the starting column address for the burst. The Mode Register sets type of burst (sequential or interleave) and the burst length (1, 2, 4, 8, full page) during the Mode Register Set Up cycle. Table 2 and 3 in the next page explain the address sequence of interleave mode and sequential mode.
W9825G6CH Addressing Sequence of Sequential Mode A column access is performed by increasing the address from the column address which is input to the device. The disturb address is varied by the Burst Length as shown in Table 2.
W9825G6CH Auto-precharge Command If A10 is set to high when the Read or Write Command is issued, then the auto-precharge function is entered. During auto-precharge, a Read Command will execute as normal with the exception that the active bank will begin to precharge automatically before all burst read cycles have been completed. Regardless of burst length, it will begin a certain number of clocks prior to the end of the scheduled burst cycle. The number of clocks is determined by CAS latency.
W9825G6CH The Power Down mode is exited by bringing CKE high. When CKE goes high, a No Operation Command is required on the next rising clock edge, depending on tCK. The input buffers need to be enabled with CKE held high for a period equal to tCKS (min) + tCK (min). No Operation Command The No Operation Command should be used in cases when the SDRAM is in a idle or a wait state to prevent the SDRAM from registering any unwanted commands between operations.
