V1.2 TS32/64/128GSSD18M-M Block Diagram 1.8" Portable Solid State Drive 5 Transcend Information Inc. V1.2 TS32/64/128GSSD18M-M Reliability Wear-Leveling algorithm 1.8" Portable Solid State Drive The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks' erase count is higher than the data blocks', it will activate the static wear leveling, replacing the not so frequently used user blocks with the high erase count free blocks. ECC algorithm The controller use BCH8 ECC algorithm per 512 bytes. BCH8 can correct up to 8 random error bits within 512 data bytes. Bad-block management When the flash encounters ECC failed, program fail or erase fail, the controller will mark the block as bad block to prevent the used of this block and caused data lost later on. 6 Transcend Information Inc. V1.2 TS32/64/128GSSD18M-M SATA Interface Out of bank signaling 1.8" Portable Solid State Drive There shall be three Out Of Band (OOB) signals used/detected by the Phy: COMRESET, COMINIT, and COMWAKE. COMINIT, COMRESET and COMWAKE OOB signaling shall be achieved by transmission of either a burst of four Gen1 ALIGNP primitives or a burst composed of four Gen1 Dwords with each Dword composed of four D24.3 characters, each burst having a duration of 160 UIOOB. Each burst is followed by idle periods (at common-mode levels), having durations as depicted in Figure 4 and Table 2. Figure 4 : OOB signals Table 2 : OOB signal times 7 Transcend Information Inc. V1.2 TS32/64/128GSSD18M-M COMRESET 1.8" Portable Solid State Drive COMRESET always originates from the host controller, and forces a hardware reset in the device. It is indicated by transmitting bursts of data separated by an idle bus condition. The OOB COMRESET signal shall consist of no less than six data bursts, including inter-burst temporal spacing. The COMRESET signal shall be: 1) Sustained/continued uninterrupted as long as the system hard reset is asserted, or 2) Started during the system hardware reset and ended some time after the negation of system hardware reset, or 3) Transmitted immediately following the negation of the system hardware reset signal. The host controller shall ignore any signal received from the device from the assertion of the hardware reset signal until the COMRESET signal is transmitted. Each burst shall be 160 Gen1 UI's long (106.7 ns) and each inter-burst idle state shall be 480 Gen1 UI's long (320 ns). A COMRESET detector looksfor four consecutive bursts with 320 ns spacing (nominal). Any spacing less than 175 ns or greater than 525 ns shall invalidate the COMRESET detector output. The COMRESET interface signal to the Phy layer shall initiate the Reset sequence shown in Figure 5 below. The interface shall be held inactive for at least 525 ns after the last burst to ensure far-end detector detects the negation properly. Figure 5 : comreset sequence Description: 1. Host/device are powered and operating normally with some form of active communication. 8 Transcend Information Inc. V1.2 TS32/64/128GSSD18M-M 2. Some condition in the host causes the host to issue COMRESET signal and puts the bus in a quiescent condition. 1.8" Portable Solid State Drive 3. Host releases COMRESET. Once the condition causing the COMRESET is released, the host releases the COMRESET 4. Device issues COMINIT - When the device detects the release of COMRESET, it responds with a COMINIT. This is also the entry point if the device is late starting. The device may initiate communications at any time by issuing a COMINIT. 5. Host calibrates and issues a COMWAKE. 6. Device responds - The device detects the COMWAKE sequence on its RX pair and calibrates its transmitter (optional). Following calibration the device sends a six burst COMWAKE sequence and then sends a continuous stream of the ALIGN sequence starting at the device's highest supported speed. After ALIGNP Dwords have been sent for 54.6us (2048 nominal Gen1 Dword times) without a response from the host as determined by detection of ALIGNP primitives received from the host, the device assumes that the host cannot communicate at that speed. If additional speeds are available the device tries the next lower supported speed by sending ALIGNP Dwords at that rate for 54.6 us (2048 nominal Gen1 Dword times.) This step is repeated for as many slower speeds as are supported. Once the lowest speed has been reached without response from the host, the device enters an error state. 7. Host locks - after detecting the COMWAKE, the host starts transmitting D10.2 characters at its lowest supported rate. Meanwhile, the host receiver locks to the ALIGN sequence and, when ready, returns the ALIGN sequence to the device at the same speed as received. A host shall be designed such that it acquires lock in 54.6us (2048 nominal Gen1 Dword times) at any given speed. The host should allow for at least 873.8 us (32768 nominal Gen1 Dword times) after detecting the release of COMWAKE to receive the first ALIGNP. This ensures interoperability with multi-generational and synchronous designs. If no ALIGNP is received within 873.8 us (32768 nominal Gen1 Dword times) the host restarts the power-on sequence - repeating indefinitely until told to stop by the Application layer. 8. Device locks - the device locks to the ALIGN sequence and, when ready, sends SYNCP indicating it is ready to start normal operation. 9. Upon receipt of three back-to-back non-ALIGNP primitives, the communication link is established and normal operation may begin. COMINIT COMINIT always originates from the drive and requests a communication initialization. It is electrically identical to the COMRESET signal except that it originates from the device and is sent to the host. It is used by the device to request a reset from the host in accordance to the sequence shown in Figure 6, below. 9 Transcend Information Inc.

V1.2 TS32/64/128GSSD18M-M 1.8" Portable Solid State Drive times) at any given speed.

V1.2 TS32/64/128GSSD18M-M Description: 1. Host/device power-off - Host and device power-off. 1.8" Portable Solid State Drive 2. Power is applied - Host side signal conditioning pulls TX and RX pairs to neutral state (common mode voltage). 3. Host issues COMRESET 4. Host releases COMRESET. Once the power-on reset is released, the host releases the COMRESET signal and puts the bus in a quiescent condition. 5.
