3. Theory of Operation 

3.1 Overview 

Figure 2 shows the operation of ICOP IM242S from the system level, including the major hardware 
blocks. 
 

 

Figure 4: ICOP IM242S Block Diagram 

 
ICOP IM242S integrates a SATA III controller and NAND flash memories. Communication with the 
host occurs through the host interface, using the standard ATA protocol. Communication with the 
flash device(s) occurs through the flash interface. 

3.2 SATA III Controller 

ICOP IM242S is designed with 

88NV1120

, a SATA III 6.0Gbps (Gen. 3) controller. The Serial ATA 

physical,  link  and  transport  layers  are  compliant  with  Serial  ATA  Gen  1,  Gen  2  and  Gen  3 
specification (Gen 3 supports 1.5Gbps/3.0Gbps/6.0Gbps data rate). The controller has 2 channels 
for flash interface. 

3.3 Error Detection and Correction 

ICOP 2.5”SATA SSD 3ME4 is designed with hardware LDPC ECC engine with hard-decision and 
soft-decision  decoding.  Low-density  parity-check  (LDPC)  codes  have  excellent  error  correcting
