LPDDR2 Array Configuration

The 4Gb Mobile Low-Power DDR2 SDRAM (LPDDR2) is a high-speed CMOS, dynamic

random-access memory containing 4,294,967,296-bits. The device is internally config-

ured as an eight-bank DRAM. Each of the x16’s 536,870,912-bit banks is organized as

16,384 rows by 2048 columns by 16 bits. Each of the x32’s 536,870,912-bit banks is or-

ganized as 16,384 rows by 1024 columns by 32 bits.

General Notes

Throughout the data sheet, figures and text refer to DQs as “DQ.” DQ should be inter-

preted as any or all DQ collectively, unless specifically stated otherwise.

“DQS” and “CK” should be interpreted as DQS_t, DQS_c and CK_t, CK_c respectively,

unless specifically stated otherwise. “BA” includes all BA pins used for a given density.

Complete functionality may be described throughout the entire document. Any page or

diagram may have been simplified to convey a topic and may not be inclusive of all re-

quirements.

Any specific requirement takes precedence over a general statement.

Any functionality not specifically stated herein is considered undefined, illegal, is not

supported, and will result in unknown operation.
