Problems solved by technology

It can be seen that using Parallel NOR FLASH and parallel PSRAM for chip packaging, the number of balls is large, and it is difficult to wire, which also causes the area of ​​the packaged memory chip to not be too small
In addition, since the area of ​​Parallel NOR FLASH is much larger than that of parallel PSRAM, the area of ​​this memory chip is mainly determined by Parallel NOR FLASH, and since the area of ​​Parallel NOR FLASH is relatively large, the area of ​​the packaged memory chip bigger

Abstract

The invention relates to a packaged memory chip and an embedded device comprising the same. The memory chip comprises a packaged SPI (serial peripheral interface) NOR FLASH and a parallel PSRAM (pseudo static random access memory); the SPI NOR FLASH comprises a clock input pin and four input and output pins; the parallel PSRAM comprises a clock input pin CLK2 and more than four address input and data input and output pins; and the four input and output pins of the SPI NOR FLASH are respectively connected with optional four of the address input and data input and output pins of the parallel PSRAM, and the CLK1 is connected with the CLK2. According to the technical scheme, the area of the packaged memory chip can be reduced.

Description

technical field [0001] The invention relates to the technical field of chip packaging, in particular to a packaged memory chip and an embedded device using the memory chip. Background technique [0002] With the increasingly diversified requirements of various portable information devices for memory characteristics, in order to solve the problem of insufficient integration and functions of a single chip, a multi-chip package (Multi Chip Package, which can package several chips in one place) has emerged. MCP) technology has the advantage that two to three chips with different characteristics can be packaged together to form a chip, which can reduce the space occupied by the chip and improve the integration and functional perfection of the chip. Samsung Electronics, Hyundai Electronics, Intel and other global heavyweight integrated circuit manufacturers have recently been optimistic about the market prospect of this type of memory, and have launched related products.
