Samsung has started production of the new high-speed low power DDR3 (LPDDR3) RAM for mobile devices. The new chips are based on 20-nm process while apparently capable of achieving performance levels comparable to RAM found on computers.
The 4Gb RAM can transmit data up to 2,133 megabits per second (Mbps) per pin, which is much more than existing LPDDR2 (800Mbps). Moreover, the new DRAM is also more power efficient, consuming 20% less power.
Samsung will offer OEMs a 2GB package with four chips stacked together that have a height of just 0.8mm. The production is expected to be ramped up later in the year so we’re guessing that first devices using this memory will be released by Christmas (though we could be wrong)…
