WebA bidirectional data strobe (DQS) is transmitted externally, along with data, for use in data capture at the receiver. DQS is a strobe transmitted by the DDR SDRAM during Reads and by the memory controller during Writes. DQS is edge- aligned with data for Reads and center-aligned with data for Writes. Web• Throughout the data sheet, the various fi gures and text refer to DQs as ¡°DQ.¡± The DQ term is to be interpreted as any and all DQ collectively, unless specifi cally stated otherwise. Additionally, each chip is divided into 2 bytes, the lower byte and upper byte. For the lower byte (DQ0¨CDQ7), DM refers to LDM and DQS refers to LDQS.

However, two pairs of data strobes, UDQS and UDQS# (upper byte) and LDQS and LDQS# (lower byte), are required by the ×16 configuration devices. A group of DQ pins must remain associated with its respective DQS and DQSn ... shrimp of the woods look alike
