1Gb Mobile DDR Part Numbering
Notes:
1. Throughout this data sheet, the various figures and text refer to DQs as “DQ.” The DQ
2. Complete functionality is described throughout the document; any page or diagram
3. Any specific requirement takes precedence over a general statement.
Due to space limitations, FBGA-packaged components have an abbreviated part
marking that is different from the part number. Micron’s FBGA Part Marking Decoder is
available at www.micron.com/decoder.
The 1Gb Mobile DDR SDRAM is a high-speed CMOS, dynamic random-access memory
containing 1,073,741,824 bits. It is internally configured as a quad-bank DRAM. Each of
the x16’s 268,435,456-bit banks is organized as 16,384 rows by 1,024 columns by 16 bits.
Each of the x32’s 268,435,456-bit banks is organized as 8,192 rows by 1,024 columns by
32 bits. In the reduced page-size (LG) option, each of the x32’s 268,435,456-bit banks are
organized as 16,384 rows by 512 columns by 32 bits.
term is to be interpreted as any and all DQ collectively, unless specifically stated
otherwise. Additionally, the x16 is divided into two bytes: the lower byte and the upper
byte. For the lower byte (DQ[7:0]), DM refers to LDM and DQS refers to LDQS. For the
upper byte (DQ[15:8]), DM refers to UDM and DQS refers to UDQS. The x32 is divided
into four bytes. For DQ[7:0], DM refers to DM0 and DQS refers to DQS0. For DQ[15:8],
DM refers to DM1 and DQS refers to DQS1. For DQ[23:16], DM refers to DM2 and
DQS refers to DQS2. For DQ[31:24], DM refers to DM3 and DQS refers to DQS3.
