Rev. 0.1 / Oct. 2003 1 Preliminary HY5Y6B6DLF(P)-xF 4Banks x1M x 16bits Synchronous DRAM DESCRIPTION The Hynix Mobile SDR is suited for non-PC application which use the batteries such as PDAs, 2.5G and 3G cellular phones with internet access and multimedia capabilities, mini-notebook, handheld PCs. The Hynix HY5Y6B6DLF(P) is a 67,108,864bit CMOS Synchronous Dynamic Random Access Memory. It is organized as 4banks of 1,048,576x16. The Mobile SDR provides for programmable options including CAS latency of 1, 2 or 3, READ or WRITE burst length of 1, 2, 4, 8, or full page, and the burst count sequence(sequential or interleave). And the Mobile SDR also provides for special programmable options including Partial Array Self Refresh of a quarter bank, a half bank, 1bank, 2banks, or all banks. The Hynix HY5Y6B6DLF(P) has the special Low Power function of Auto TCSR(Temperature Compensated Self Refresh) to reduce self refresh current consumption. Since an internal temperature sensor is implanted, it enables to automatically adjust refresh rate according to temperature without external EMRS command. A burst of Read or Write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst Read or Write command on any cycle(This pipelined design is not restricted by a 2N rule). Deep Power Down Mode is a additional operating mode for Mobile SDR. This mode can achieve maximum power reduction by removing power to the memory array within each SDR. By using this feature, the system can cut off alomost all DRAM power without adding the cost of a power switch and giving up mother-board power-line layout flexibility.

Power must be applied to VDD and VDDQ(simultaneously). The clock signal must be started at the same time. After power up, an initial pause of 200 usec is required. And a precharge all command will be issued to the Mobile SDR. Then, 8 or more Auto refresh cycles will be provided. After the Auto refresh cycles are completed, a mode register set(MRS) command will be issued to program the specific mode of operation (Cas Latency, Burst length, etc.) And a extended mode register set command will be issued to program specific mode of self refresh operation(PASR). The following these cycles, the Mobile SDR is ready for normal opeartion. Programming the registers Mode Register The mode register contains the specific mode of operation of the Mobile SDR. This register includes the selection of a burst length(1, 2, 4, 8, Full Page), a cas latency(1, 2 or 3), a burst type. The mode register set must be done before any activate command after the power up sequence. Any contents of the mode register be altered by re-programming the mode register through the execution of mode register set command. Extended Mode Register The extended mode register contains the specific features of self refresh opeartion of the Mobile SDR. This register includes the selection of partial arrays to be refreshed(half array, quarter array, etc.). The extended mode register set must be done before any activate command after the power up sequence. Any contents of the mode register be altered by re-programming the mode register through the execution of extended mode register set command. Bank(Row) Active The Bank Active command is used to activate a row in a specified bank of the device. This command is initiated by activating CS, RAS and deasserting CAS, WE at the positive edge of the clock. The value on the BA1 and BA0 selects the bank, and the value on the A0-A11 selects the row. This row remains active for column access until a precharge command is issued to that bank. Read and write opeartions can only be initiated on this activated bank after the minimum tRCD time is passed from the activate command. Read The READ command is used to initiate the burst read of data. This command is initiated by activating CS, CAS, and deasserting WE, RAS at the positive edge of the clock. BA1 and BA0 inputs select the bank, A7-A0 address inputs select the sarting column location. The value on input A10 determines whether or not Auto Precharge is used. If Auto Precharge is selected the row being accessed will be precharged at the end of the READ burst; if Auto Precharge is not selected, the row will remain active for subsequent accesses. The length of burst and the CAS latency will be determined by the values programmed during the MRS command. Write The WRITE command is used to initiate the burst write of data. This command is initiated by activating CS, CAS, WE and deasserting RAS at the positive edge of the clock. BA1 and BA0 inputs select the bank, A7-A0 address inputs select the starting column location. The value on input A10 determines whether or not Auto Precharge is used. If Auto Precharge is selected the row being accessed will be precharged at the end of the WRITE burst; if Auto Precharge is not selected, the row will remain active for subsequent accesses. Rev. 0.1 / Oct. 2003 8 Preliminary HY5Y6B6DLF(P)-xF 4Banks x 1M x 16bits Synchronous DRAM Precharge The Precharge command is used to close the open row in a particular bank or the open row in all banks. When the precharge command is issued with address A10, high, then all banks will be precharged, and If A10 is low, the open row in a particular bank will be precharged. The bank(s) will be available when the minimum tRP time is met after the precharge command is issued. Auto Precharge The Auto Precharge command is issued to close the open row in a particular bank after READ or WRITE operation. If A10 is high when a READ or WRITE command is issued, the READ or WRITE with Auto Precharge is initiated. Burst Termination The Burst Termination is used to terminate the burst operation. This function can be accomplished by asserting a Burst Stop command or a Precharge command during a burst READ or WRITE operation. The Precharge command interrupts a burst cycle and close the active bank, and the Burst Stop command terminates the existing burst operation leave the bank open. Data Mask The Data Mask comamnd is used to mask READ or WRITE data. During a READ operation, When this command is issued, data ouputs are disabled and become high impedance after two clock delay. During a WRITE operation, When this command is issued, data inputs can't be written with no clock delay. Clock Suspend The Clock Suspend command is used to suspend the internal clock of Mobile SDR. During normal access mode, CKE is keeping High. When CKE is low, it freezes the internal clock and extends data Read and Write operations. Power Down The Power Down command is used to reduce standby current. Before this command is issued, all banks must be precharged and tRP must be passed after a precharge command. Once the Power Down command is initiated by keeping CKE low, all of the input buffer except CKE are gated off. Auto Refresh The Auto Refresh command is used during normal operation and is similar to CBR refresh in Coventional DRAMs. This command must be issued each time a refresh is required. When an Auto Refresh command is issued , the address bits is ''Don't care'', because the specific address bits is generated by internal refresh address counter. Self Refresh The Self Refresh command is used to retain cell data in the Mobile SDR. In the Self Refresh mode, the Mobile SDR operates refresh cycle asynchronously. The Self Refresh command is initiated like an Auto Refresh command except CKE is disabled(Low). The Mobile SDR can accomplish an special Self Refresh operation by the specific modes(PASR) programmed in extended mode registers. The Mobile SDR can control the refresh rate automatically by the temperature value of Auto TCSR(Temperature Compensated Self Refresh) to reduce self refresh current and select the memory array to be refreshed by the value of PASR(Partial Array Self Refresh). The Mobile SDR can reduce the self refresh current(IDD6) by using these two modes. Deep Power Down The Deep Power Down Mode is used to achieve maximum power reduction by cutting the power of the whole memory array of the devices. For more information, see the special operation for Low Power consumption of this data sheet.

Rev. 0.1 / Oct. 2003 24 Preliminary HY5Y6B6DLF(P)-xF 4Banks x 1M x 16bits Synchronous DRAM Special Operation for Low Power Consumption Deep Power Down Mode Deep Power Down Mode is an operating mode to achieve maximum power reduction by cutting the power of the whole memory array of the devices. Data will not be retained once the device enters Deep Power Down Mode. Full initialization is required when the device exits from Deep Power Down Mode. Truth Table Current State Command CKEn-1 CKEn CS RAS CAS WE Idle Deep Power Down Entry H L L H H L Deep Power Down Deep Power Down Exit L H X X X X Deep Power Down Mode Entry The Deep Power Down Mode is entered by having CS and WE held low with RAS and CAS high at the rising edge of the clock, while CKE is low.

After the exit, the following sequence is needed to enter a new command. 1. Maintain NOP input conditions for a minimum of 200usec 2. Issue precharge commands for all banks of the device 3. Issue 8 or more auto refresh commands 4. Issue a mode register set command to initialize the mode register 5. Issue an extended mode register set command to initialize the extended mode register The following timing diagram illustrates deep power down mode exit sequence.
