TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive Reliability Wear-Leveling algorithm 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.
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive SATA Interface Out of bank signaling 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.
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive COMRESET 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.
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive 2. Some condition in the host causes the host to issue COMRESET 3. Host releases COMRESET. Once the condition causing the COMRESET is released, the host releases the COMRESET signal and puts the bus in a quiescent condition. 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.
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive Figure 6 : cominit sequence Description: 1. Host/device are powered and operating normally with some form of active communication. 2. Some condition in the device causes the device to issues a COMINIT 3. Host calibrates and issues a COMWAKE. 4. Device responds – The device detects the COMWAKE sequence on its RX pair and calibrates its transmitter (optional).
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive 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. 6.
TS32/64/128GSSD18M-M 1.8” Portable Solid State Drive Description: 1. Host/device power-off - Host and device power-off. 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. Device issues COMINIT – When the device detects the release of COMRESET, it responds with a COMINIT.
