PRECHARGEThe PRECHARGE command is used to deactivate the open row in a particular bank orthe open row in all banks. The bank(s) will be available for a subsequent row activationa specified time (t RP) after the PRECHARGE command is issued, except in the case ofconcurrent auto precharge, where a READ or WRITE command to a different bank is al-lowed as long as it does not interrupt the data transfer in the current bank and does notviolate any other timing parameters. After a bank has been precharged, it is in the idlestate and must be activated prior to any READ or WRITE commands being issued tothat bank. A PRECHARGE command is allowed if there is no open row in that bank (idlestate) or if the previously open row is already in the process of precharging. However,the precharge period will be determined by the last PRECHARGE command issued tothe bank.REFRESHREFRESH is used during normal operation of the DDR2 SDRAM and is analogous toCAS#-before-RAS# (CBR) REFRESH. All banks must be in the idle mode prior to issuinga REFRESH command. This command is nonpersistent, so it must be issued each timea refresh is required. The addressing is generated by the internal refresh controller. Thismakes the address bits a “Don’t Care” during a REFRESH command.SELF REFRESHThe SELF REFRESH command can be used to retain data in the DDR2 SDRAM, even ifthe rest of the system is powered down. When in the self refresh mode, the DDR2SDRAM retains data without external clocking. All power supply inputs (including Vref)must be maintained at valid levels upon entry/exit and during SELF REFRESH opera-tion.The SELF REFRESH command is initiated like a REFRESH command except CKE isLOW. The DLL is automatically disabled upon entering self refresh and is automaticallyenabled upon exiting self refresh.Mode Register (MR)The mode register is used to define the specific mode of operation of the DDR2 SDRAM.This definition includes the selection of a burst length, burst type, CAS latency, operat-ing mode, DLL RESET, write recovery, and power-down mode, as shown in Figure 36(page 79). Contents of the mode register can be altered by re-executing the LOADMODE (LM) command. If the user chooses to modify only a subset of the MR variables,all variables must be programmed when the command is issued.The MR is programmed via the LM command and will retain the stored information un-til it is programmed again or until the device loses power (except for bit M8, which isself-clearing). Reprogramming the mode register will not alter the contents of the mem-ory array, provided it is performed correctly.The LM command can only be issued (or reissued) when all banks are in the prechargedstate (idle state) and no bursts are in progress. The controller must wait the specifiedtime t MRD before initiating any subsequent operations such as an ACTIVATE com-mand. Violating either of these requirements will result in an unspecified operation.Figure 53: Bank Read – Without Auto PrechargeDon’t Care Transitioning DataNotes: 1.NOP commands are shown for ease of illustration; other commands may be valid atthese times.2.BL = 4 and AL = 0 in the case shown.3.The PRECHARGE command can only be applied at T6 if t RAS (MIN) is met.4.READ-to-PRECHARGE = AL + BL/2 - 2CK + MAX (t RTP/t CK or 2CK).5.Disable auto precharge.6.“Don’t Care” if A10 is HIGH at T5.7.I/O balls, when entering or exiting High-Z, are not referenced to a specific voltage level,but to when the device begins to drive or no longer drives, respectively.8.DO n = data-out from column n ; subsequent elements are applied in the programmed order.Figure 67: Data Input TimingDQSDQS#DM DQCKCK#T1T0T1n T2T2n T3T4T3n Don’t CareTransitioning Data Notes: 1.t DSH (MIN) generally occurs during t DQSS (MIN).2.t DSS (MIN) generally occurs during t DQSS (MAX).3.Subsequent rising DQS signals must align to the clock within t DQSS.4.WRITE command issued at T0.5.For x16, LDQS controls the lower byte and UDQS controls the upper byte.6.WRITE command with WL = 2 (CL = 3, AL = 0) issued at T0.PRECHARGEPrecharge can be initiated by either a manual PRECHARGE command or by an autopre-charge in conjunction with either a READ or WRITE command. Precharge will deacti-vate the open row in a particular bank or the open row in all banks. The PRECHARGE operation is shown in the previous READ and WRITE operation sections.During a manual PRECHARGE command, the A10 input determines whether one or all banks are to be precharged. In the case where only one bank is to be precharged, bank address inputs determine the bank to be precharged. When all banks are to be pre-charged, the bank address inputs are treated as “Don’t Care.”Once a bank has been precharged, it is in the idle state and must be activated prior to any READ or WRITE commands being issued to that bank. When a single-bank PRE-CHARGE command is issued, t RP timing applies. When the PRECHARGE (ALL) com-mand is issued, t RPA timing applies, regardless of the number of banks opened.2Gb: x4, x8, x16 DDR2 SDRAM PRECHARGE。
