|---|---|---|
A 1.0 V 8 Gbit LPDDR4 SDRAM with 3.2 Gbps/pin speed and integrated ECC engine for sub-1 V DRAM core is presented. DRAM internal read-modify-write operation for data masked write makes the integrated ECC engine possible in a commodity DRAM. Time interleaved latency and IO control circuits enable 1.0 V operation at target speed. To reach 3.2 Gbps with improved power efficiency over conventional mobile DRAMs, the following IO features are introduced: Low voltage swing terminated logic drivers with VOH level calibration and periodic ZQ calibration, unmatched DQ/DQS scheme and DQS oscillator for DQS tree delay tracking. This chip is fabricated in 25 nm DRAM process on 88.1 mm 2 die area. |
